- ------------------------------------------------------------------------ Debian Security Advisory DSA-1709-1 security@debian.org http://www.debian.org/security/ Thijs Kinkhorst January 21, 2009 http://www.debian.org/security/faq - ------------------------------------------------------------------------
Package : shadow Vulnerability : race condition Problem type : local Debian-specific: no CVE Id(s) : CVE-2008-5394 Debian Bug : 505271
Paul Szabo discovered that login, the system login tool, did not correctly handle symlinks while setting up tty permissions. If a local attacker were able to gain control of the system utmp file, they could cause login to change the ownership and permissions on arbitrary files, leading to a root privilege escalation.
For the stable distribution (etch), this problem has been fixed in version 4.0.18.1-7+etch1.
For the unstable distribution (sid), this problem has been fixed in version 4.1.1-6.
We recommend that you upgrade your shadow package.
Upgrade instructions - --------------------
