Background ========== The Free Lossless Audio Codec (FLAC) library is the reference implementation of the FLAC audio file format. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/flac < 1.3.1-r1 >= 1.3.1-r1 Description =========== A stack-based buffer overflow flaw has been discovered in FLAC. Impact ====== A remote attacker could entice a user to open a specially crafted .flac file using an application linked against FLAC, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All FLAC users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/flac-1.3.1-r1" Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages.
