Vulnerability from fkie_nvd - Published: 2013-11-20 14:12 - Updated: 2025-04-11 00:51
Severity ?
Summary
lighttpd before 1.4.33 does not check the return value of the (1) setuid, (2) setgid, or (3) setgroups functions, which might cause lighttpd to run as root if it is restarted and allows remote attackers to gain privileges, as demonstrated by multiple calls to the clone function that cause setuid to fail when the user process limit is reached.
