Debian DSA-1974-1 : gzip - several vulnerabilities
Medium Nessus Plugin ID 44839
The remote Debian host is missing a security-related update.
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.
Upgrade the gzip packages. 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.
