CVE-2013-4143 describes a bypass vulnerability in xlockmore versions prior to 5.43. Specifically, the checkPasswd and checkGroupXlockPasswds functions fail to correctly handle NULL return values from the crypt or dispcrypt functions (as implemented in glibc 2.17+), allowing attackers to bypass the screen lock through invalid salts. This vulnerability has a low severity CVSS score of 2.1, indicating local access with low attack complexity and a potential impact of partial availability loss. There is no evidence of active exploitation, no known public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
