Affected: Mozilla Firefox, Mozilla Firefox ESR

Calling `PK11_Encrypt()` in NSS using CKM_CHACHA20 and the same buffer for input and output can result in plaintext on an Intel Sandy Bridge processor. In Firefox this only affects the QUIC header protection feature when the connection is using the ChaCha20-Poly1305 cipher suite. The most likely outcome is connection failure, but if the connection persists despite the high packet loss it could be possible for a network observer to identify packets as coming from the same source despite a network path change. This vulnerability affects Firefox < 129, Firefox ESR < 115.14, and Firefox ESR < 128.1.

Affected: Ubuntu:20.04:LTS: firefox

Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. (CVE-2024-7518, CVE-2024-7521, CVE-2024-7524, CVE-2024-7526, CVE-2024-7527, CVE-2024-7528, CVE-2024-7529, CVE-2024-7530, CVE-2024-7531)

It was discovered that Firefox did not properly manage certain memory operations when processing graphics shared memory. An attacker could potentially exploit this issue to escape the sandbox. (CVE-2024-7519)

Nan Wang discovered that Firefox did not properly handle type check in WebAssembly. An attacker could potentially exploit this issue to execute arbitrary code. (CVE-2024-7520)

Irvan Kurniawan discovered that Firefox did not properly check an attribute value in the editor component, leading to an out-of-bounds read vulnerability. An attacker could possibly use this issue to cause a denial of service or expose sensitive information. (CVE-2024-7522)
