This advisory covers four security vulnerabilities in webkit2gtk3 affecting Red Hat Enterprise Linux 8.2 AUS. The vulnerabilities include unexpected process crashes (CVE-2024-54479, CVE-2024-54502, CVE-2024-54508) and memory corruption (CVE-2024-54505) triggered by processing maliciously crafted web content. These issues relate to weaknesses identified by CWEs such as CWE-404 (improper resource shutdown), CWE-125 (out-of-bounds read), CWE-843 (type confusion), and CWE-20 (input validation). Red Hat has released updated packages (webkit2gtk3-2.46.5-1.el8_2) to fix these issues.
