TITLE

gzip of zgrep Vulnerable to arbitrary command execution

DESCRIPTION

zgrep in gzip before 1.3.5 does not properly sanitize arguments, which allows local users to execute arbitrary commands via filenames that are injected into a sed script. ------------ This vulnerability information is a summary of multiple vulnerabilities released at the same time. Please note that the contents of vulnerability information other than the title are included. ------------ GNU zip (gzip) Is a utility that compresses and decompresses files. grep Run zgrep Or unzip the compressed file gunzip Each tool is packaged. Gzip 1.2.4 Previously, there were several security issues: 1) gzip 1.2.4 Included before zgrep There is a problem that does not properly sanitize arguments. (CAN-2005-0758) Details are currently unknown, but local attackers who exploit this issue zgrep An arbitrary command may be executed by passing an intentional file name to. 2) gzip 1.2.4 Previously, when decompressing a compressed file, there was a problem that caused a race condition between writing the decompressed file and changing permissions. (CAN-2005-0988) A local attacker who exploits this issue could alter the permissions of an arbitrary file by replacing the decompressed file with a hard link to the arbitrary file at a specific time. 3) gzip 1.2.4 Included before gunzip Is -N When decompressing a compressed file with a flag, there is a problem that the validity of the file name is not properly checked. (CAN-2005-1228) A remote attacker who exploits this issue ".." Send a compressed file that is a compressed file containing an intentional character string to the target user gzip Inducing a directory traversal attack by inducing unpacking with.Please refer to the “Overview” for the impact of this vulnerability. The 'zgrep' utility is reportedly affected by an arbitrary command-execution vulnerability. An attacker may execute arbitrary commands through zgrep command arguments to potentially gain unauthorized access to the affected computer. Note that this issue poses a security threat only if the arguments originate from a malicious source. This issue affects zgrep 1.2.4; other versions may be affected as well. ---------------------------------------------------------------------- Want a new IT Security job?

This makes it possible to have a file extracted to an arbitrary location outside the current directory via directory traversal attacks. The vulnerability has been reported in version 1.2.4, 1.2.4a, 1.3.3, 1.3.4 and 1.3.5. SOLUTION: Do not extract untrusted ".gz" files with the "-N" flag.

The zgrep utility improperly sanitizes arguments, which may come from an untrusted source (CAN-2005-0758). Impact ====== These vulnerabilities could allow arbitrary command execution, changing the permissions of arbitrary files, and installation of files to an aribitrary location in the filesystem. Workaround ========== There is no known workaround at this time. Resolution ========== All gzip users should upgrade to the latest stable version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/gzip-1.3.5-r6" References ========== [ 1 ] CAN-2005-0758 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0758 [ 2 ] CAN-2005-0988 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0988 [ 3 ] CAN-2005-1228 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1228 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200505-05.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
