Last modified Jun 16, 2026

CVE-2007-2293 is a vulnerability of currently unknown severity. Multiple stack-based buffer overflows in the process_sdp function in chan_sip.c of the SIP channel T.38 SDP parser in Asterisk before 1.4.3 allow remote attackers to execute arbitrary code via a long (1) T38FaxRateManagement or (2) T38FaxUdpEC SDP parameter in an SIP message, as demonstrated using SIP INVITE.. EPSS estimates a 23.88% chance of exploitation in the next 30 days.
