Package : gzip
Vulnerability : several
Problem type : local (remote)
Debian-specific: no
CVE Ids : CVE-2009-2624 CVE-2010-0001
Debian Bug : 507263
Several vulnerabilities have been found in gzip, the GNU compression
utilities. The Common Vulnerabilities and Exposures project identifies
the following problems:
CVE-2009-2624
Thiemo Nagel discovered a missing input sanitation flaw in the way gzip
used to decompress data blocks for dynamic Huffman codes, which could
lead to the execution of arbitrary code when trying to decompress a
crafted archive. This issue is a reappearance of CVE-2006-4334 and only
affects the lenny version.
CVE-2010-0001
Aki Helin discovered an integer underflow when decompressing files that
are compressed using the LZW algorithm. This could lead to the execution
of arbitrary code when trying to decompress a crafted LZW compressed
gzip archive.
For the stable distribution (lenny), these problems have been fixed in
version 1.3.12-6+lenny1.
For the oldstable distribution (etch), these problems have been fixed in
version 1.3.5-15+etch1.
For the testing distribution (squeeze) and the unstable distribution
(sid), these problems will be fixed soon.
We recommend that you upgrade your gzip packages.
Upgrade instructions
