The libFLAC project, an open source library implementing reference encoders and decoders for native FLAC and Ogg FLAC audio content, suffers from multiple implementation issues. In particular, a stack overflow and a heap overflow condition, which may result in arbitrary code execution, can be triggered by passing a maliciously crafted .flac file to the libFLAC decoder. Affected version: libFLAC <= 1.3.0 The following packages were identified as affected as they statically include libFLAC in their own packages. Max <= 0.9.1 Cog <= 0.07 cinelerra <= 4.6 JUCE <= 3.1.0 (juce_audio_formats module) Fixed version: libFLAC >= 1.3.1 Max N/A Cog N/A cinelerra N/A JUCE N/A Credit: vulnerability report from Michele Spagnuolo of Google Security Team <mikispag AT google.com> CVE: CVE-2014-8962 (stack overflow) CVE-2014-9028 (heap overflow) Timeline: 2014-11-12: heap overflow report received 2014-11-12: contacted maintainer 2014-11-14: patch provided by maintainer 2014-11-17: reporter confirms patch 2014-11-20: stack overflow vulnerability reported 2014-11-21: assigned CVE (heap overflow) 2014-11-22: contacted affected vendors 2014-11-23: contacted additional affected vendors 2014-11-25: advisory release References: https://git.xiph.org/?p=flac.git;a=commit;h=5b3033a2b355068c11fe637e14ac742d273f076e https://git.xiph.org/?p=flac.git;a=commit;h=fcf0ba06ae12ccd7c67cee3c8d948df15f946b85 Permalink: http://www.ocert.org/advisories/ocert-2014-008.html -- Daniele Bianco Open Source Computer Security Incident Response Team <danbia@...rt.org> http://www.ocert.org GPG Key 0x9544A497 GPG Key fingerprint = 88A7 43F4 F28F 1B9D 6F2D 4AC5 AE75 822E 9544 A497
