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-2024-1547,
CVE-2024-1548, CVE-2024-1549, CVE-2024-1550, CVE-2024-1553, CVE-2024-1554,
CVE-2024-1555, CVE-2024-1557)

Alfred Peters discovered that Firefox did not properly manage memory when
storing and re-accessing data on a networking channel. An attacker could
potentially exploit this issue to cause a denial of service.
(CVE-2024-1546)

Johan Carlsson discovered that Firefox incorrectly handled Set-Cookie
response headers in multipart HTTP responses. An attacker could
potentially exploit this issue to inject arbitrary cookie values.
(CVE-2024-1551)

Gary Kwong discovered that Firefox incorrectly generated codes on 32-bit
ARM devices, which could lead to unexpected numeric conversions or
undefined behaviour. An attacker could possibly use this issue to cause a
denial of service. (CVE-2024-1552)

Ronald Crane discovered that Firefox did not properly manage memory when
accessing the built-in profiler. An attacker could potentially exploit
this issue to cause a denial of service. (CVE-2024-1556)
