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.
CVE-2006-5444
Score elevated to 9.0 because EPSS predicts 87% probability of exploitation within the next 30 days (top 0.5% of all CVEs). Confidence: see factors.
- High exploitation likelihood — EPSS 85%
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
