Description

The most pager can automatically open files compressed with gzip, bzip2 and (in Debian) LZMA. Alberto Garcia discovered that Debian's version of most was susceptible for a shell injection attack that could be exploited to run arbitrary commands on the user's computer.

For Debian 7 'Wheezy', these problems have been fixed in version 5.0.0a-2.2.

We recommend that you upgrade your most packages.

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