What is CVE-2017-16872?
CVE-2017-16872 is a critical vulnerability in Debian Debian Linux, published on 17 Nov 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
An issue was discovered in Teluu pjproject (pjlib and pjlib-util) in PJSIP before 2.7.1. Parsing the numeric header fields in a SIP message (like cseq, ttl, port, etc.) all had the potential to overflow, either causing unintended values to be captured or, if the values were subsequently converted back to strings, a buffer overrun. This will lead to a potential exploit using carefully crafted invalid values.
