CVE-2015-3276 (GCVE-0-2015-3276)

Vulnerability from cvelistv5 – Published: 2015-12-07 20:00 – Updated: 2024-08-06 05:39

Summary

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.

Severity

No CVSS data available.
