Last modified Jun 17, 2026

CVE-2015-3276 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The nss_parse_ciphers function in libraries/libldap/tls_m.c in OpenLDAP does not properly parse OpenSSL-style multi-keyword mode cipher strings, which might cause a weaker than intended cipher to be used and allow remote attackers to have unspecified impact via unknown vectors.. EPSS estimates a 5.33% chance of exploitation in the next 30 days.
