FreeSWITCH mod_sofia: stack buffer overflow from an over-long SIP To-header user

Özet

Türkçe özeti yalnızca kritik ve yüksek önemdeki açıklar için hazırlıyoruz. Bu açık için kaynağın kendi açıklamasını gösteriyoruz.

FreeSWITCH is an open-source software telecommunications platform. From 1.10.0 until 1.11.1, a stack-based buffer overflow in  mod_sofia  when generating dialog-event notifications. A peer can establish a dialog with an excessively long SIP To-header user part and subsequently subscribe to that entity’s dialog events, causing the stored value to overflow a fixed-size stack buffer. Exploitation requires presence or shared-appearance management to be enabled and normally requires valid profile credentials, unless subscription authentication is disabled. The overflow can terminate the FreeSWITCH process and all active calls. This vulnerability is fixed in version 1.11.2.
