tag_insight = "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.";
