CVE-2021-43303

Name of the Vulnerable Software and Affected Versions PJSIP (affected versions not specified)

Description The issue is related to a buffer overflow in the PJSUA API when calling the pjsua call dump function. An attacker-controlled buffer argument may cause a buffer overflow if an output buffer smaller than 128 characters is supplied, regardless of the maxlen argument. This could allow a remote attacker to execute arbitrary code. The vulnerability is associated with a boundary error in the PJSUA API, potentially leading to memory corruption.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
