-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Testing Security Advisory DTSA-27-1 January 20th, 2006 Neil McGovern - -------------------------------------------------------------------------- Package : fuse Vulnerability : potential data corruption when installed seduid root Problem-Scope : local Debian-specific: No CVE ID : CVE-2005-3531 Thomas Biege discovered that fusermount in FUSE before 2.4.1, if installed setuid root, allows local users to corrupt /etc/mtab and possibly modify mount options by performing a mount over a directory whose name contains certain special characters Successful exploitation could result in a denial of service if mount options become unusable. An attacker can also exploit this issue to add arbitrary mount points that could grant the attacker read and possibly write access to otherwise restricted or privileged mount points. Other attacks are also possible. For the testing distribution (etch) this is fixed in version 2.3.0-4.2etch1 For the unstable distribution (sid) this is fixed in version 2.4.1-0.1 This upgrade is recommended if you use fuse. The Debian testing security team does not track security issues for the stable (sarge) and oldstable (woody) distributions. If stable is vulnerable, the Debian security team will make an announcement once a fix is ready.
