Description: | 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, these problems have been fixed in version 1.3.12-6+lenny1. For the oldstable distribution, these problems have been fixed in version 1.3.5-15+etch1. For the testing distribution and the unstable distribution, these problems will be fixed soon. We recommend that you upgrade your gzip packages. |
