CVE-2023-28099

OpenSIPS has vulnerability in the ds_is_in_list() function

5.9 Medium

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.9 and 3.2.6, if ds_is_in_list() is used with an invalid IP address string (NULL is illegal input), OpenSIPS will attempt to print a string from a random address (stack garbage), which could lead to a crash. All users of ds_is_in_list() without the $si variable as 1st parameter could be affected by this vulnerability to a larger, lesser or no extent at all, depending if the data passed to the function is a valid IPv4 or IPv6 address string or not. Fixes will are available starting with the 3.1.9 and 3.2.6 minor releases. There are no known workarounds.
