CVE-2013-4122

no score yetEPSS 3.6%

cmu cyrus-sasl: no CVSS score yet. EPSS 3.6% chance of exploitation in the next 30 days.

Cyrus SASL 2.1.23, 2.1.26, and earlier does not properly handle when a NULL value is returned upon an error by the crypt function as implemented in glibc 2.17 and later, which allows remote attackers to cause a denial of service (thread crash and consumption) via (1) an invalid salt or, when FIPS-140 is enabled, a (2) DES or (3) MD5 encrypted password, which triggers a NULL pointer dereference.

EPSS: 3.6% chance of exploitation in the next 30 days; higher than 89% of CVEs (scores of 2026-10-31)
