Red Hat Security Advisory: gstreamer1-plugins-good security update
Two security vulnerabilities have been identified in the gstreamer1-plugins-good package used in Red Hat Enterprise Linux 9. These include an unsigned integer underflow in avidemux FUJIFILM strd parsing leading to out-of-bounds read/write (CVE-2026-73433) and an out-of-bounds read in avidemux vprp video field descriptor parsing (CVE-2026-73434). Red Hat has issued a security update to address these issues, rated as having moderate impact. The vulnerabilities could potentially lead to memory corruption due to improper bounds checking. The update is available for multiple architectures and variants of Red Hat Enterprise Linux 9.
