|Description||Integer signedness error in the base64_decode function in the HTTP authentication functionality (http_auth.c) in lighttpd 1.4 before 1.4.30 and 1.5 before SVN revision 2806 allows remote attackers to cause a denial of service (segmentation fault) via crafted base64 input that triggers an out-of-bounds read with a negative index.|
|Source||CVE (at NVD; oss-sec, fulldisc, OSVDB, EDB, Metasploit, Red Hat, Ubuntu, Gentoo, SuSE, Mageia, more)|
|NVD severity||medium (attack range: remote)|
Vulnerable and fixed packages
The table below lists information on source packages.
|lighttpd (PTS)||squeeze (security), squeeze||1.4.28-2+squeeze1.6||fixed|
|wheezy, wheezy (security)||1.4.31-4+deb7u3||fixed|
The information below is based on the following data on fixed versions.
the announcement says that the debian package is not affected, but there are no additional patches that would cause different behavior (i.e. the base64_reverse_table is the same in debian and upstream), so if upstream is affected, so too is the debian package
