CVE-2008-2119 describes a denial-of-service vulnerability in Asterisk Open Source versions 1.0.x and 1.2.x before 1.2.29, and Business Edition A.x.x and B.x.x before B.2.5.3, when pedantic SIP parsing is enabled. Remote attackers can crash the Asterisk daemon by sending a malformed SIP INVITE message lacking a From header, due to improper handling of empty strings and NULL pointers during URI decoding. This vulnerability has a CVSS score of 4.3, indicating a medium attack complexity and partial availability impact. While not listed in CISA's KEV catalog, an exploit module for ExploitDB exists (EDB-5749), suggesting public exploit code availability, though there is no evidence of active exploitation or significant community discussion.
