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-2023-5169,
CVE-2023-5170, CVE-2023-5171, CVE-2023-5172, CVE-2023-5175, CVE-2023-5176)
Ronald Crane discovered that Firefox did not properly manage memory when
non-HTTPS Alternate Services (network.http.altsvc.oe) is enabled. An
attacker could potentially exploit this issue to cause a denial of service.
(CVE-2023-5173)
ClΓ©ment Lecigne discovered that Firefox did not properly manage memory when
handling VP8 media stream. An attacker-controlled VP8 media stream could
lead to a heap buffer overflow in the content process, resulting in a
denial of service, or possibly execute arbitrary code. (CVE-2023-5217)
