Description Johannes Segitz 2014-11-26 11:35:17 UTC

rh#1168146

t was found that when the UID and GID were changed in the <changeowner> section of the /etc/icecast.xml file, the supplementary groups were left in place. This could allow an attacker to escalate their privileges if the <changeowner> configuration was used.

The fix was added in version 2.4.0.

Comment 2 Takashi Iwai 2014-11-26 21:14:38 UTC

I submitted the fixed packages to openSUSE 12.3 and 13.1.
oS 13.2 has already icecast 2.4.0, and SLE don't contain this package.

openSUSE-SU-2014:1591-1: An update that fixes two vulnerabilities is now available.
