Description

This security bulletin contains information about 1 security vulnerability.


1) NULL pointer dereference (CVE-ID: CVE-2022-1249)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in pesign's cms_set_pw_data() function of the cms_common.c file. The function fails to handle the NULL pwdata invocation from daemon.c, which leads to an explicit NULL dereference and crash on all attempts to daemonize pesign. A local user can perform a denial of service (DoS) attack.
