CVE-2017-16872

https://notcve.org/view.php?id=CVE-2017-16872

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. Se ha descubierto un error en Teluu pjproject (pjlib y pjlib-util) en PJSIP, en versiones anteriores a la 2.7.1. Analizando los campos de cabeceras numéricas en un mensaje SIP (como cseq, ttl, port, etc.), todos tienen el potencial de causar una saturación de búfer, ya sea haciendo que se capturen valores no planeados o si los valores se volvieron a convertir a cadenas posteriormente. • https://trac.pjsip.org/repos/milestone/release-2.7.1 https://trac.pjsip.org/repos/ticket/2056 https://www.debian.org/security/2018/dsa-4170 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
