Updated most packages has been released for Debian 7 LTS

Package : most
Version : 5.0.0a-2.2
CVE ID : CVE-2016-1253
Debian Bug : 848132

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.
