Description Huzaifa S. Sidhpurwala 2013-09-27 04:46:11 UTC

A flaw was found in the way nss read uninitialized data, when there was a decryption failure. A remote attacker could use this flaw to cause denial of service for applications linked with the nss library (application crash)
The vulnerable code was added in NSS 3.14.3 to fix the lucky-13 issue (CVE-2013-1620). This issue is resolved in nss-3.15.2
