Background ========== libass is a portable subtitle renderer for the ASS/SSA (Advanced Substation Alpha/Substation Alpha) subtitle format. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/libass < 0.15.1 >= 0.15.1 Description =========== A one-byte buffer overwrite in ASS font decoding could trigger an assertion failure resulting in denial of service. Impact ====== An attacker with control over the ASS track input to libass via an application using it could trigger a denial of service. Workaround ========== There is no known workaround at this time. Resolution ========== All libass users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libass-0.15.1" References ========== [ 1 ] CVE-2020-36430 https://nvd.nist.gov/vuln/detail/CVE-2020-36430 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202208-13 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
