OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.7 and 3.2.4, a specially crafted Authorization header causes OpenSIPS to crash or behave in an unexpected way due to a bug in the function parse_param_name()
. This issue was discovered while performing coverage guided fuzzing of the function parse_msg. The AddressSanitizer identified that the issue occurred in the function q_memchr()
which is being called by the function parse_param_name()
. This issue may cause erratic program behaviour or a server crash. It affects configurations containing
functions that make use of the affected code, such as the function www_authorize()
. Versions 3.1.7 and 3.2.4 contain a fix.
