Recent GNU Gzip Security Vulnerabilities

An arbitrary file write vulnerability was found in GNU gzip's zgrep utility

CVE-2022-1271 8.8 - High - August 31, 2022

An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.

Improper Input Validation

Integer underflow in the unlzw function in unlzw.c in gzip before 1.4 on 64-bit platforms, as used in ncompress and probably others, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted archive

CVE-2010-0001 - January 29, 2010

Integer underflow in the unlzw function in unlzw.c in gzip before 1.4 on 64-bit platforms, as used in ncompress and probably others, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted archive that uses LZW compression, leading to an array index error.

Numeric Errors

gzip before 1.3 in Solaris 8, when called with the -f or -force flags, will change the permissions of files

CVE-2004-1349 - October 04, 2004

gzip before 1.3 in Solaris 8, when called with the -f or -force flags, will change the permissions of files that are hard linked to the target files, which allows local users to view or modify these files.
