Alpine: multiple pjproject packages: security update to 2.12-r0

critical Tenable Cloud Security Plugin ID 424347

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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. (CVE-2021-37706)

- PJSIP is a free and open source multimedia communication library written in the C language implementing
standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In various parts of PJSIP, when
error/failure occurs, it is found that the function returns without releasing the currently held locks.
This could result in a system deadlock, which cause a denial of service for the users. No release has yet
been made which contains the linked fix commit. All versions up to an including 2.11.1 are affected. Users
may need to manually apply the patch. (CVE-2021-41141)

- Stack overflow in PJSUA API when calling pjsua_player_create. An attacker-controlled 'filename' argument
may cause a buffer overflow since it is copied to a fixed-size stack buffer without any size validation.
(CVE-2021-43299)

- Stack overflow in PJSUA API when calling pjsua_recorder_create. An attacker-controlled 'filename' argument
may cause a buffer overflow since it is copied to a fixed-size stack buffer without any size validation.
(CVE-2021-43300)
