Debian Security Advisory DSA 794-1 [email protected]
http://www.debian.org/security/ Martin Schulze
September 1st, 2005 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
Package : polygen
Vulnerability : programming error
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2005-2656
Debian Bug : 325468
Justin Rye noticed that polygen generates precompiled grammar objects
world-writable, which can be exploited by a local attacker to at least
fill up the filesystem.
The old stable distribution (woody) does not contain the polygen package.
For the stable distribution (sarge) this problem has been fixed in
version 1.0.6-7sarge1.
For the unstable distribution (sid) this problem has been fixed in
version 1.0.6-9.
We recommend that you upgrade your polygen package.
Upgrade Instructions
