Original advisory details:

 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-2023-6865,
 CVE-2023-6857, CVE-2023-6858, CVE-2023-6859, CVE-2023-6866, CVE-2023-6867,
 CVE-2023-6861, CVE-2023-6869, CVE-2023-6871, CVE-2023-6872, CVE-2023-6863,
 CVE-2023-6864, CVE-2023-6873)

 DoHyun Lee discovered that Firefox did not properly manage memory when used
 on systems with the Mesa VM driver. An attacker could potentially exploit
 this issue to execute arbitrary code. (CVE-2023-6856)

 George Pantela and Hubert Kario discovered that Firefox using multiple NSS
 NIST curves which were susceptible to a side-channel attack known as
 'Minerva'. An attacker could potentially exploit this issue to obtain
 sensitive information. (CVE-2023-6135)

 Andrew Osmond discovered that Firefox did not properly validate the textures
 produced by remote decoders. An attacker could potentially exploit this
 issue to escape the sandbox. (CVE-2023-6860)");
