DESCRIPTION:
Two security issues have been reported in GNU gv, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges and by malicious people to potentially
compromise a vulnerable system.

1) An error in the handling of temporary files when processing PDF
files can be exploited to overwrite arbitrary files via symlink
attacks.

2) An error exists due to the application invoking "gs" without the
"-P-" command line option, which can be exploited to execute
arbitrary postscript commands if a user is tricked into opening a
specially crafted file in an attacker controlled directory.

SOLUTION:
Update to version 3.7.0.
