Bug#812363: wheezy-pu: package giflib/4.1.6-10+deb7u1
Package: release.debian.org
Severity: normal
Tags: wheezy
User: release.debian.org@packages.debian.org
Usertags: pu
Hi,
I'd like to fix CVE-2015-7555 via wheezy-pu since the bug is fixed in
Squeeze LTS and we try to not introduce new security issues when people
upgrade (the Debian security team marked this CVE as no-dsa).
Please find the debdiff attached.
Cheers,
-- Guido
