libsamplerate: User-assisted execution of arbitrary code

Background

Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converter for audio.

Description

Russell O’Connor reported a buffer overflow in src/src_sinc.c related to low conversion ratios.

Impact

A remote attacker could entice a user or automated system to process a specially crafted audio file possibly leading to the execution of arbitrary code with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All libsamplerate users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/libsamplerate-0.1.4"
