Integer overflow in the get_input function in the Skinny channel driver (chan_skinny.c) in Asterisk 1.0.x before 1.0.12 and 1.2.x before 1.2.13, as used by Cisco SCCP phones, allows remote attackers to execute arbitrary code via a certain dlen value that passes a signed integer comparison and leads to a heap-based buffer overflow.

Security readout for executives and security teams

This is an old but serious Asterisk flaw. A remote attacker could abuse the Skinny/SCCP phone channel handling to trigger memory corruption and potentially run code on the phone server. Business urgency is highest for legacy Asterisk systems still supporting Cisco SCCP phones. Exposure is likely limited to legacy Asterisk deployments running the Skinny channel driver for Cisco SCCP phones, especially unfixed 1.0.x or 1.2.x systems. The bundle does not establish exposure for newer Asterisk branches. Prioritize remediation where legacy Asterisk remains operational. Remote code execution on PBX infrastructure can disrupt communications and create a foothold, but urgency depends on whether old Skinny/SCCP support is still present and reachable. Mitigation focus: Upgrade Asterisk 1.0.x to 1.0.12 or later if still in use.; Upgrade Asterisk 1.2.x to 1.2.13 or later if still in use.; Apply distro vendor packages from Debian, Gentoo, SUSE, or relevant maintainers..
