Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.

A type confusion vulnerability can occur when manipulating JavaScript objects due to issues in Array.pop. This can allow for an exploitable crash. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Firefox ESR < 60.7.1, Firefox < 67.0.3, and Thunderbird < 60.7.2.

In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure.

The plain text serializer used a fixed-size array for the number of <ol> elements it could process; however it was possible to overflow the static-sized array leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.

Mozilla developers reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3.

When Python was installed on Windows, a python file being served with the MIME type of text/plain could be executed by Python instead of being opened as a text file when the Open option was selected upon download. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 72.

In SaltStack Salt through 2019.2.0, the salt-api NET API with the ssh client enabled is vulnerable to command injection. This allows an unauthenticated attacker with network access to the API endpoint to execute arbitrary code on the salt-api host.

Multiple cross-site request forgery (CSRF) vulnerabilities in Bugzilla before 3.2.10, 3.4.x before 3.4.10, 3.6.x before 3.6.4, and 4.0.x before 4.0rc2 allow remote attackers to hijack the authentication of arbitrary users for requests related to (1) adding a saved search in buglist.cgi, (2) voting in votes.cgi, (3) sanity checking in sanitycheck.cgi, (4) creating or editing a chart in chart.cgi, (5) column changing in colchange.cgi, and (6) adding, deleting, or approving a quip in quips.cgi.

During the initialization of a new content process, a pointer offset can be manipulated leading to memory corruption and a potentially exploitable crash in the parent process. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.

When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to 7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

GdkPixBuf (aka gdk-pixbuf), possibly 2.32.2, as used by GNOME Nautilus 3.14.3 on Ubuntu 16.04, allows attackers to cause a denial of service (stack corruption) or possibly have unspecified other impact via a crafted file folder.

The WebAudio `OscillatorNode` object was susceptible to a stack buffer overflow. This could have led to a potentially exploitable crash. This vulnerability affects Firefox < 122.

LoaderXM::load in LoaderXM.cpp in milkyplay in MilkyTracker 1.02.00 has a stack-based buffer overflow.

In Netwide Assembler (NASM) 2.14rc0, preproc.c allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.

In Netwide Assembler (NASM) 2.14rc0, there are multiple heap use after free vulnerabilities in the tool nasm. The related heap is allocated in the token() function and freed in the detoken() function (called by pp_getline()) - it is used again at multiple positions later that could cause multiple damages. For example, it causes a corrupted double-linked list in detoken(), a double free or corruption in delete_Token(), and an out-of-bounds write in detoken(). It has a high possibility to lead to a remote code execution attack.

A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of the function, it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.

ModuleEditor::convertInstrument in tracker/ModuleEditor.cpp in MilkyTracker 1.02.00 has a heap-based buffer overflow.

ImageMagick 7.0.8-50 Q16 has a heap-based buffer over-read at MagickCore/threshold.c in AdaptiveThresholdImage because a width of zero is mishandled.

RubyGems version 2.6.12 and earlier is vulnerable to a DNS hijacking vulnerability that allows a MITM attacker to force the RubyGems client to download and install gems from a server that the attacker controls.

Out of bounds write in SQLite in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

ImageMagick 7.0.8-50 Q16 has a stack-based buffer overflow at coders/pnm.c in WritePNMImage because of off-by-one errors.

ImageMagick 7.0.8-50 Q16 has a stack-based buffer overflow at coders/pnm.c in WritePNMImage because of a misplaced strncpy and an off-by-one error.

ImageMagick 7.0.8-50 Q16 has a heap-based buffer overflow at MagickCore/statistic.c in EvaluateImages because of mishandling columns.

Gnome gdk-pixbuf 2.36.8 and older is vulnerable to several integer overflow in the gif_get_lzw function resulting in memory corruption and potential code execution

A potentially exploitable crash in "EnumerateSubDocuments" while adding or removing sub-documents. This vulnerability affects Firefox ESR < 45.6 and Thunderbird < 45.6.

Use-after-free while manipulating the "navigator" object within WebVR. Note: WebVR is not currently enabled by default. This vulnerability affects Firefox < 50.1.

Privilege escalation in the IPC component. This vulnerability was fixed in Firefox 149 and Thunderbird 149.

An issue was discovered in Squid 4.0.23 through 4.7. When checking Basic Authentication with HttpHeader::getAuth, Squid uses a global buffer to store the decoded data. Squid does not check that the decoded length isn't greater than the buffer, leading to a heap-based buffer overflow with user controlled data.

The inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving left shifts of negative integers.

Because Firefox did not implement the <code>unsafe-hashes</code> CSP directive, an attacker who was able to inject markup into a page otherwise protected by a Content Security Policy may have been able to inject executable script. This would be severely constrained by the specified Content Security Policy of the document. This vulnerability affects Firefox < 108.

A potential use-after-free vulnerability existed in SVG Images if the Refresh Driver was destroyed at an inopportune time. This could have lead to memory corruption or a potentially exploitable crash. *Note*: This advisory was added on December 13th, 2022 after discovering it was inadvertently left out of the original advisory. The fix was included in the original release of Firefox 106. This vulnerability affects Firefox < 106.

Mozilla developers and community members Lukas Bernhard, Gabriele Svelto, Randell Jesup, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 107. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 108.

POST requests made by NPAPI plugins, such as Flash, that receive a status 308 redirect response can bypass CORS requirements. This can allow an attacker to perform Cross-Site Request Forgery (CSRF) attacks. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.

Files with the .JNLP extension used for "Java web start" applications are not treated as executable content for download prompts even though they can be executed if Java is installed on the local system. This could allow users to mistakenly launch an executable binary locally. This vulnerability affects Firefox < 67.
