gzip: arbitrary command execution [LWN.net]

Package(s):

gzip

CVE #(s):

CAN-2005-0758

Created:

August 1, 2005

Updated:

January 10, 2007

Description:

zgrep in gzip before 1.3.5 does not handle shell metacharacters like '|' and '&' properly when they occurred in input file names. This could be exploited to execute arbitrary commands with user privileges if zgrep is run in an untrusted directory with specially crafted file names.

USN-161-1 applies to bzgrep in the bzip2 package, not gzip. Both scripts had the same problem.
