Debian Security Advisory DSA-2164-1 [email protected]
http://www.debian.org/security/ Nico Golde
February 16, 2011 http://www.debian.org/security/faq
Package : shadow
Vulnerability : insufficient input sanitization
Problem type : local
Debian-specific: no
CVE ID : CVE-2011-0721
Kees Cook discovered that the chfn and chsh utilities do not properly
sanitize user input that includes newlines. An attacker could use this
to to corrupt passwd entries and may create users or groups in NIS
environments.
Packages in the oldstable distribution (lenny) are not affected by this
problem.
For the stable distribution (squeeze), this problem has been fixed in
version 1:4.1.4.2+svn3283-2+squeeze1.
For the testing (wheezy) and unstable (sid) distributions, this problem
will be fixed soon.
We recommend that you upgrade your shadow packages.
