Debian Security Advisory DSA 446-1 security@debian.org

Package : synaesthesia
Vulnerability : insecure file creation
Problem-Type : local
Debian-specific: no
CVE Ids : CAN-2004-0160
During an audit, Ulf Harnhammar discovered a vulnerability in
synaesthesia, a program which represents sounds visually.
synaesthesia created its configuration file while holding root
privileges, allowing a local user to create files owned by root and
writable by the user's primary group. This type of vulnerability can
usually be easily exploited to execute arbitary code with root
privileges by various means.
For the current stable distribution (woody) this problem has been
fixed in version 2.1-2.1woody1.
The unstable distribution (sid) is not affected by this problem, because
synaesthesia is no longer setuid.
We recommend that you update your synaesthesia package.
