A spoofing vulnerability exists when the ASP.NET Core fails to properly sanitize web requests.

A denial of service vulnerability exists when the ASP.NET Core fails to properly validate web requests. NOTE: Microsoft has not commented on third-party claims that the issue is that the TextEncoder.EncodeCore function in the System.Text.Encodings.Web package in ASP.NET Core Mvc before 1.0.4 and 1.1.x before 1.1.3 allows remote attackers to cause a denial of service by leveraging failure to properly calculate the length of 4-byte characters in the Unicode Non-Character range.

curl before version 7.51.0 doesn't parse the authority component of the URL correctly when the host name part ends with a '#' character, and could instead be tricked into connecting to a different host. This may have security implications if you for example use an URL parser that follows the RFC to check for allowed domains before using curl to request them.

This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

The "Mark of the Web" was not correctly saved on Windows when files with very long names were downloaded from the Internet. Without the Mark of the Web data, the security warning that Windows displays before running executables downloaded from the Internet is not shown. Note: This attack only affects Windows operating systems. Other operating systems are unaffected. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.

Firefox will accept any registered Program ID as an external protocol handler and offer to launch this local application when given a matching URL on Windows operating systems. This should only happen if the program has specifically registered itself as a "URL Handler" in the Windows registry. *Note: This issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.

Microsoft Lync for Mac 2011 fails to properly validate certificates, allowing remote attackers to alter server-client communications, aka "Microsoft Lync for Mac Certificate Validation Vulnerability."

An issue was discovered in Suricata 5.0.0. It was possible to bypass/evade any tcp based signature by faking a closed TCP session using an evil server. After the TCP SYN packet, it is possible to inject a RST ACK and a FIN ACK packet with a bad TCP Timestamp option. The client will ignore the RST ACK and the FIN ACK packets because of the bad TCP Timestamp option. Both linux and windows client are ignoring the injected packets.

A spoofing vulnerability exists when Azure Stack fails to validate certain requests, aka 'Azure Stack Spoofing Vulnerability'.

Vidalia bundle before 0.1.2.18, when running on Windows and Mac OS X, installs Privoxy with a configuration file (config.txt or config) that contains insecure (1) enable-remote-toggle and (2) enable-edit-actions settings, which allows remote attackers to bypass intended access restrictions and modify configuration.

In the Windows 10 April 2018 Update, Windows Defender SmartScreen honors the "SEE_MASK_FLAG_NO_UI" flag associated with downloaded files and will not show any UI. Files that are unknown and potentially dangerous will be allowed to run because SmartScreen will not prompt the user for a decision, and if the user is offline all files will be allowed to be opened because Windows won't prompt the user to ask what to do. Firefox incorrectly sets this flag when downloading files, leading to less secure behavior from SmartScreen. Note: this issue only affects Windows 10 users running the April 2018 update or later. It does not affect other Windows users or other operating systems. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.

The Microsoft Outlook mail client identifies the physical path of the sender's machine within a winmail.dat attachment to Rich Text Format (RTF) files.

Vidalia bundle before 0.1.2.18, when running on Windows, installs Privoxy with a configuration file (config.txt or config) that contains an insecure enable-remote-http-toggle setting, which allows remote attackers to bypass intended access restrictions and modify configuration.

libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily.

The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more.

Rollup 18 for Microsoft Exchange Server 2010 SP3 and previous versions has an SSRF vulnerability via the username parameter in /owa/auth/logon.aspx in the OWA (Outlook Web Access) login page.

Sennheiser HeadSetup 7.3.4903 places Certification Authority (CA) certificates into the Trusted Root CA store of the local system, and publishes the private key in the SennComCCKey.pem file within the public software distribution, which allows remote attackers to spoof arbitrary web sites or software publishers for several years, even if the HeadSetup product is uninstalled. NOTE: a vulnerability-assessment approach must check all Windows systems for CA certificates with a CN of 127.0.0.1 or SennComRootCA, and determine whether those certificates are unwanted.
