Debian Security Advisory DSA-3221-1 [email protected]
http://www.debian.org/security/ Salvatore Bonaccorso
April 12, 2015 http://www.debian.org/security/faq
Package : das-watchdog
CVE ID : CVE-2015-2831
Debian Bug : 781806
Adam Sampson discovered a buffer overflow in the handling of the
XAUTHORITY environment variable in das-watchdog, a watchdog daemon to
ensure a realtime process won't hang the machine. A local user can
exploit this flaw to escalate his privileges and execute arbitrary
code as root.
For the stable distribution (wheezy), this problem has been fixed in
version 0.9.0-2+deb7u1.
For the unstable distribution (sid), this problem has been fixed in
version 0.9.0-3.1.
We recommend that you upgrade your das-watchdog packages.
