Hello, I have found two buffer overflows in SoX. They occur when the sox or play commands handle malicious .WAV files. Versions 12.17.4, 12.17.3 and 12.17.2 are vulnerable to these overflows. 12.17.1, 12.17 and 12.16 are some versions that are not. SoX may not be the most security critical program, but it is possible to exploit this. Some attack vectors are social engineering (I have used play to play .WAV files from untrusted sources several times before I found this), programs that use SoX to play data from the net (examples include JiveAudio and vmail), and people who put play in their mailcap files (so it plays sound files in MIME messages as soon as the messages are opened). It is also interesting to note that xmms can play .WAV files with this type of data just fine. ... // Ulf Harnhammar Debian Security Audit Project http://www.debian.org/security/audit/ RHEL is handled by bug 128158 The RHEL entry contains POC wav and the patch.
