Name of the Vulnerable Software and Affected Versions
lighttpd versions 1.4 before 1.4.30
lighttpd versions 1.5 before SVN revision 2806
Description
The issue is caused by an integer signedness error in the base64 decode function within the HTTP authentication functionality. This error allows remote attackers to trigger a denial of service, resulting in a segmentation fault, by providing crafted base64 input that causes an out-of-bounds read with a negative index.
Recommendations
For lighttpd versions 1.4 before 1.4.30, update to version 1.4.30 or later.
For lighttpd versions 1.5 before SVN revision 2806, update to SVN revision 2806 or later.
