libsndfile - arbitrary code execution

Two vulnerabilities have been found in libsndfile, a library to read
and write sampled audio data. The Common Vulnerabilities and Exposures
project identified the following problems:

• CVE-2009-1788
  Tobias Klein discovered that the VOC parsing routines suffer of a heap-based
  buffer overflow which can be triggered by an attacker via a crafted VOC
  header.
• CVE-2009-1791
  The vendor discovered that the AIFF parsing routines suffer of a heap-based
  buffer overflow similar to CVE-2009-1788 which can be triggered by an attacker
  via a crafted AIFF header.

In both cases the overflowing data is not completely attacker controlled but
still leads to application crashes or under some circumstances might still
lead to arbitrary code execution.

For the oldstable distribution (etch), this problem has been fixed in
version 1.0.16-2+etch2.

For the stable distribution (lenny), this problem has been fixed in
version 1.0.17-4+lenny2.

For the testing distribution (squeeze), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 1.0.20-1.

We recommend that you upgrade your libsndfile packages.
