TITLE

PJSIP  Integer Underflow Vulnerability in

DESCRIPTION

PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions if the incoming STUN message contains an ERROR-CODE attribute, the header length is not checked before performing a subtraction operation, potentially resulting in an integer underflow scenario. This issue affects all users that use STUN. A malicious actor located within the victim’s network may forge and send a specially crafted UDP (STUN) message that could remotely execute arbitrary code on the victim’s machine. Users are advised to upgrade as soon as possible. There are no known workarounds. PJSIP Exists in an integer underflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Asterisk Project Security Advisory - AST-2022-004 Product Asterisk Summary pjproject: possible integer underflow on STUN message Nature of Advisory Arbitrary code execution Susceptibility Remote unauthenticated sessions Severity Major Exploits Known Yes Reported On March 3, 2022 Reported By Sauw Ming Posted On March 4, 2022 Last Updated On March 3, 2022 Advisory Contact kharwell AT sangoma DOT com CVE Name CVE-2021-37706 Description The header length on incoming STUN messages that contain an ERROR-CODE attribute is not properly checked. This can result in an integer underflow. Note, this requires ICE or WebRTC support to be in use with a malicious remote party.

Buffer overflows and other programming errors could be exploited for information disclosure or the execution of arbitrary code. Special care should be taken when upgrading to this new upstream release. Some configuration files and options have changed in order to remedy certain security vulnerabilities. Most notably the pjsip TLS listener only accepts TLSv1.3 connections in the default configuration now. This can be reverted by adding method=tlsv1_2 to the transport in pjsip.conf. See also https://issues.asterisk.org/jira/browse/ASTERISK-29017. For the stable distribution (bullseye), these problems have been fixed in version 1:16.28.0~dfsg-0+deb11u1. We recommend that you upgrade your asterisk packages.
