A buffer overflow vulnerability in FLAC could lead to execution of arbitrary code or Denial of Service.
|Package||media-libs/flac on all architectures|
|Affected versions||< 1.3.1-r1|
|Unaffected versions||>= 1.3.1-r1|
The Free Lossless Audio Codec (FLAC) library is the reference implementation of the FLAC audio file format.
A stack-based buffer overflow flaw has been discovered in FLAC.
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.
There is no known workaround at this time.
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.
