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.");
