`AppendEncodedAttributeValue(), ExtraSpaceNeededForAttrEncoding()` and `AppendEncodedCharacters()` could have experienced integer overflows, causing underallocation of an output buffer leading to an out of bounds write. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
The permission prompt input delay could expire while the window is not in focus. This makes it vulnerable to clickjacking by malicious websites. This vulnerability affects Firefox < 124, Firefox ESR < 115.10, and Thunderbird < 115.10.
Using a markup injection an attacker could have stolen nonce values. This could have been used to bypass strict content security policies. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could potentially allow an attacker to recover the private data. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
The encrypted subject of an email message could be incorrectly and permanently assigned to an arbitrary other email message in Thunderbird's local cache. Consequently, when replying to the contaminated email message, the user might accidentally leak the confidential subject to a third-party. While this update fixes the bug and avoids future message contamination, it does not automatically repair existing contaminations. Users are advised to use the repair folder functionality, which is available from the context menu of email folders, which will erase incorrect subject assignments. This vulnerability affects Thunderbird < 115.8.1.
Mozilla Necko, as used in Firefox, SeaMonkey, and other applications, performs DNS prefetching of domain names contained in links within local HTML documents, which makes it easier for remote attackers to determine the network location of the application's user by logging DNS requests. NOTE: the vendor disputes the significance of this issue, stating "I don't think we necessarily need to worry about that case."
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 3.5.x before 3.5.6, SeaMonkey before 2.0.1, and Thunderbird allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Unspecified vulnerability in the browser engine in Mozilla Firefox before 3.0.16, SeaMonkey before 2.0.1, and Thunderbird allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Multiple unspecified vulnerabilities in the JavaScript engine in Mozilla Firefox 3.5.x before 3.5.6, SeaMonkey before 2.0.1, and Thunderbird allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, allows remote attackers to send authenticated requests to arbitrary applications by replaying the NTLM credentials of a browser user.
