Antisip libosip2 4.1.0 Heap Buffer Overflow / Denial Of Service

Credit: bshastry
Risk: High
Local: No
Remote: Yes
CVE: N/A
CWE: CWE-119

Antisip's libosip2 v4.1.0 is vulnerable to heap buffer overflows in the following functions while parsing SIP messages and leads to a DoS if glibc hardening is enabled. 1. *osip_body_to_str* 2. *_osip_message_to_str* All files for reproducing the issues have been filed in the bug tracker [1][2] and have since been fixed in upcoming osip version 5.0.0 [3]. I wonder if the report is sufficient to mandate CVEs. Feedback welcome.
