Debian -- Security Information Matt Zimmerman February 21st, 2004 Debian -- Debian security FAQ - -------------------------------------------------------------------------- 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.
