The huft_build function in inflate.c in gzip before 1.3.13 creates a hufts (aka huffman) table that is too small, which allows remote attackers to cause a denial of service (application crash or infinite loop) or possibly execute arbitrary code via a crafted archive. NOTE: this issue is caused by a CVE-2006-4334 regression.

The remote Solaris system is missing necessary patches to address security updates :

This update fixes CVE-2009-2624 and CVE-2010-0001 vulnerabilities.

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.

The following bugs have been fixed :

  - Specially crafted gzip archives could lead to gzip     allocating a too small huffman table. Attackers could     exploit that to crash gzip (CVE-2009-2624). Specially     crafted gzip archives could trigger integer overflows.
    Attackers could exploit that to crash gzip or     potentially execute arbitrary code (CVE-2010-0001). Only     64bit architectures are affected by this flaw.

Specially crafted gzip archives could lead to gzip allocating a too small huffman table. Attackers could exploit that to crash gzip (CVE-2009-2624).

Specially crafted gzip archives could trigger integer overflows.
Attackers could exploit that to crash gzip or potentially execute arbitrary code (CVE-2010-0001). Only 64bit architectures are affected by this flaw.

It was discovered that gzip incorrectly handled certain malformed compressed files. If a user or automated system were tricked into opening a specially crafted gzip file, an attacker could cause gzip to crash or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-2624)

Aki Helin discovered that gzip incorrectly handled certain malformed files compressed with the Lempel-Ziv-Welch (LZW) algorithm. If a user or automated system were tricked into opening a specially crafted gzip file, an attacker could cause gzip to crash or possibly execute arbitrary code with the privileges of the user invoking the program.
(CVE-2010-0001).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple vulnerabilities has been found and corrected in gzip :

A missing input sanitation flaw was found in the way gzip used to decompress data blocks for dynamic Huffman codes. A remote attacker could provide a specially crafted gzip compressed data archive, which once opened by a local, unsuspecting user would lead to denial of service (gzip crash) or, potentially, to arbitrary code execution with the privileges of the user running gzip (CVE-2009-2624).

An integer underflow leading to array index error was found in the way gzip used to decompress files / archives, compressed with the Lempel-Ziv-Welch (LZW) compression algorithm. A remote attacker could provide a specially crafted LZW compressed gzip archive, which once decompressed by a local, unsuspecting user would lead to gzip crash, or, potentially to arbitrary code execution with the privileges of the user running gzip (CVE-2010-0001).

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers.

The updated packages have been patched to correct these issues.
