Shotwell version 0.22.0 (and possibly other versions) is vulnerable to a TLS/SSL certification validation flaw resulting in a potential for man in the middle attacks.

In GNOME grilo though 0.3.13, grl-net-wc.c does not enable TLS certificate verification on the SoupSessionAsync objects it creates, leaving users vulnerable to network MITM attacks. NOTE: this is similar to CVE-2016-20011.

In GNOME libgda through 6.0.0, gda-web-provider.c does not enable TLS certificate verification on the SoupSessionSync objects it creates, leaving users vulnerable to network MITM attacks. NOTE: this is similar to CVE-2016-20011.

An issue was discovered in GNOME Evolution before 3.35.91. By using the proprietary (non-RFC6068) "mailto?attach=..." parameter, a website (or other source of mailto links) can make Evolution attach local files or directories to a composed email message without showing a warning to the user, as demonstrated by an attach=. value.

The tiff_document_render() and tiff_document_get_thumbnail() functions in the TIFF document backend in GNOME Evince through 3.32.0 did not handle errors from TIFFReadRGBAImageOriented(), leading to uninitialized memory use when processing certain TIFF image files.

Gnome Online Accounts (GOA) 3.6.x before 3.6.3 and 3.7.x before 3.7.91, does not properly validate SSL certificates when creating accounts for providers who use the libsoup library, which allows man-in-the-middle attackers to obtain sensitive information such as credentials by sniffing the network. NOTE: this issue exists because of an incomplete fix for CVE-2013-0240.

Gnome Online Accounts (GOA) 3.4.x, 3.6.x before 3.6.3, and 3.7.x before 3.7.5, does not properly validate SSL certificates when creating accounts such as Windows Live and Facebook accounts, which allows man-in-the-middle attackers to obtain sensitive information such as credentials by sniffing the network.

GSocketClient in GNOME GLib through 2.62.4 may occasionally connect directly to a target address instead of connecting via a proxy server when configured to do so, because the proxy_addr field is mishandled. This bug is timing-dependent and may occur only sporadically depending on network delays. The greatest security relevance is in use cases where a proxy is used to help with privacy/anonymity, even though there is no technical barrier to a direct connection. NOTE: versions before 2.60 are unaffected.

GNOME Evolution before 3.2.3 allows user-assisted remote attackers to read arbitrary files via the attachment parameter to a mailto: URL, which attaches the file to the email.

evolution-data-server3 3.0.3 through 3.2.1 used insecure (non-SSL) connection when attempting to store sent email messages into the Sent folder, when the Sent folder was located on the remote server. An attacker could use this flaw to obtain login credentials of the victim.

Mozilla Firefox before 2.0.0.8 and SeaMonkey before 1.1.5, when running on Linux systems with gnome-vfs support, might allow remote attackers to read arbitrary files on SSH/sftp servers that accept key authentication by creating a web page on the target server, in which the web page contains URIs with (1) smb: or (2) sftp: schemes that access other files from the server.

GNOME librsvg version before commit c6ddf2ed4d768fd88adbea2b63f575cd523022ea contains a Improper input validation vulnerability in rsvg-io.c that can result in the victim's Windows username and NTLM password hash being leaked to remote attackers through SMB. This attack appear to be exploitable via The victim must process a specially crafted SVG file containing an UNC path on Windows.

In GNOME libgfbgraph through 0.2.4, gfbgraph-photo.c does not enable TLS certificate verification on the SoupSessionSync objects it creates, leaving users vulnerable to network MITM attacks. NOTE: this is similar to CVE-2016-20011.

In GNOME evolution-rss through 0.3.96, network-soup.c does not enable TLS certificate verification on the SoupSessionSync objects it creates, leaving users vulnerable to network MITM attacks. NOTE: this is similar to CVE-2016-20011.

In GNOME libzapojit through 0.0.3, zpj-skydrive.c does not enable TLS certificate verification on the SoupSessionSync objects it creates, leaving users vulnerable to network MITM attacks. NOTE: this is similar to CVE-2016-20011.

The S/MIME specification allows a Cipher Block Chaining (CBC) malleability-gadget attack that can indirectly lead to plaintext exfiltration, aka EFAIL.

The ntlm_challenge function in the NTLM SASL authentication mechanism in camel/camel-sasl-ntlm.c in Camel in Evolution Data Server (aka evolution-data-server) 2.24.5 and earlier, and 2.25.92 and earlier 2.25.x versions, does not validate whether a certain length value is consistent with the amount of data in a challenge packet, which allows remote mail servers to read information from the process memory of a client, or cause a denial of service (client crash), via an NTLM authentication type 2 packet with a length value that exceeds the amount of packet data.

GNOME Nautilus before 3.23.90 allows attackers to spoof a file type by using the .desktop file extension, as demonstrated by an attack in which a .desktop file's Name field ends in .pdf but this file's Exec field launches a malicious "sh -c" command. In other words, Nautilus provides no UI indication that a file actually has the potentially unsafe .desktop extension; instead, the UI only shows the .pdf extension. One (slightly) mitigating factor is that an attack requires the .desktop file to have execute permission. The solution is to ask the user to confirm that the file is supposed to be treated as a .desktop file, and then remember the user's answer in the metadata::trusted field.

The _rsvg_css_normalize_font_size function in librsvg 2.40.2 allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via circular definitions in an SVG document.

The gdk-pixbuf configuration in Mozilla Firefox before 43.0 on Linux GNOME platforms incorrectly enables the JasPer decoder, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted JPEG 2000 image.

The _rsvg_node_poly_build_path function in rsvg-shapes.c in librsvg before 2.40.7 allows context-dependent attackers to cause a denial of service (out-of-bounds heap read) via an odd number of elements in a coordinate pair in an SVG document.

librsvg before 2.40.12 allows context-dependent attackers to cause a denial of service (infinite loop, stack consumption, and application crash) via cyclic references in an SVG document.

A flaw was found in Caribou due to a regression of CVE-2020-25712 fix. An attacker could use this flaw to bypass screen-locking applications that leverage Caribou as an input mechanism. The highest threat from this vulnerability is to system availability.

The GDM daemon in GNOME Display Manager (GDM) before 2.14.13, 2.16.x before 2.16.7, 2.18.x before 2.18.4, and 2.19.x before 2.19.5 does not properly handle NULL return values from the g_strsplit function, which allows local users to cause a denial of service (persistent daemon crash) via a crafted command to the daemon's socket, related to (1) gdm.c and (2) gdmconfig.c in daemon/, and (3) gdmconfig.c and (4) gdmflexiserver.c in gui/.

A flaw was found in NetworkManager in versions before 1.30.0. Setting match.path and activating a profile crashes NetworkManager. The highest threat from this vulnerability is to system availability.

evince is missing a check on number of pages which can lead to a segmentation fault

Orca has arbitrary code execution due to insecure Python module load

gnome-keyring does not discard stored secrets when using gnome_keyring_lock_all_sync function

libgdata before 0.10.2 and 0.11.x before 0.11.1 does not validate SSL certificates, which allows remote attackers to obtain user names and passwords via a man-in-the-middle (MITM) attack with a spoofed certificate.

GNOME Rhythmbox 0.11.5 allows remote attackers to cause a denial of service (segmentation fault and crash) via a playlist (.pls) file with a long Title field, possibly related to the g_hash_table_lookup function in b-playlist-manager.c.

An issue was discovered in GNOME gnome-desktop 3.26, 3.28, and 3.30 prior to 3.30.2.2, and 3.32 prior to 3.32.1.1. A compromised thumbnailer may escape the bubblewrap sandbox used to confine thumbnailers by using the TIOCSTI ioctl to push characters into the input buffer of the thumbnailer's controlling terminal, allowing an attacker to escape the sandbox if the thumbnailer has a controlling terminal. This is due to improper filtering of the TIOCSTI ioctl on 64-bit systems, similar to CVE-2019-10063.

gnome-shell 3.22 through 3.24.1 mishandles extensions that fail to reload, which can lead to leaving extensions enabled in the lock screen. With these extensions, a bystander could launch applications (but not interact with them), see information from the extensions (e.g., what applications you have opened or what music you were playing), or even execute arbitrary commands. It all depends on what extensions a user has enabled. The problem is caused by lack of exception handling in js/ui/extensionSystem.js.

gdk-pixbuf through 2.31.1 has GIF loader buffer overflow when initializing decompression tables due to an input validation flaw

The "insert-blank-characters" capability in caps.c in gnome-terminal (vte) before 0.28.1 allows remote authenticated users to cause a denial of service (CPU and memory consumption and crash) via a crafted file, as demonstrated by a file containing the string "\033[100000000000000000@".

Acrobat Reader versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by an input validation vulnerability when decoding a crafted codec that could result in the disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Improper access control vulnerability in Camera prior to versions 11.1.02.16 in Android R(11), 10.5.03.77 in Android Q(10) and 9.0.6.68 in Android P(9) allows untrusted applications to take a picture in screenlock status.

The AgentTicketForward feature in Open Ticket Request System (OTRS) before 2.4.7 does not properly remove inline images from HTML e-mail messages, which allows remote attackers to obtain potentially sensitive image information in opportunistic circumstances by reading a forwarded message in a standard e-mail client.

The importScripts Web Worker method in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x before 3.1.1, and SeaMonkey before 2.0.6 does not verify that content is valid JavaScript code, which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted HTML document.

The TeX filter in Moodle 1.6 before 1.6.9+, 1.7 before 1.7.7+, 1.8 before 1.8.9, and 1.9 before 1.9.5 allows user-assisted attackers to read arbitrary files via an input command in a "$$" sequence, which causes LaTeX to include the contents of the file.

Unspecified vulnerability in the product view functionality in VirtueMart 1.0.13a and earlier allows remote attackers to read arbitrary files via vectors related to a template file.

Insufficient data validation in dialogs in Google Chrome on OS X prior to 86.0.4240.75 allowed a remote attacker to obtain potentially sensitive information from disk via a crafted HTML page.

Firefox 1.5.0.2 does not fix all test cases associated with CVE-2006-1729, which allows remote attackers to read arbitrary files by inserting the target filename into a text box, then turning that box into a file upload control.

A vulnerability in the Cisco Network Plug and Play application of Cisco IOS 12.4 through 15.6 and Cisco IOS XE 3.3 through 16.4 could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data by using an invalid certificate. The vulnerability is due to insufficient certificate validation by the affected software. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt confidential information on user connections to the affected software. Cisco Bug IDs: CSCvc33171.

In the previous mitigations for Spectre, the resolution or precision of various methods was reduced to counteract the ability to measure precise time intervals. In that work PerformanceNavigationTiming was not adjusted but it was found that it could be used as a precision timer. This vulnerability affects Thunderbird < 60, Firefox ESR < 60.1, and Firefox < 61.
