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.
