Debian Security Advisory DSA 730-1 [email protected]

- --------------------------------------------------------------------------
Package : bzip2
Vulnerability : race condition
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2005-0953
Debian Bug : 303300
Imran Ghory discovered a race condition in bzip2, a high-quality
block-sorting file compressor and decompressor. When decompressing a
file in a directory an attacker has access to, bunzip2 could be
tricked to set the file permissions to a different file the user has
permissions to.
For the stable distribution (woody) this problem has been fixed in
version 1.0.2-1.woody2
For the testing distribution (sarge) this problem has been fixed in
version 1.0.2-6.
For the unstable distribution (sid) this problem has been fixed in
version 1.0.2-6.
We recommend that you upgrade your bzip2 packages.
