Severity ?
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
An issue was discovered in Teluu pjproject (pjlib and pjlib-util) in PJSIP before 2.7.1. The ioqueue component may issue a double key unregistration after an attacker initiates a socket connection with specific settings and sequences. Such double key unregistration will trigger an integer overflow, which may cause ioqueue backends to reject future key registrations.
