CVE-2014-4911
First published: Tue Jul 22 2014(Updated: )
The ssl_decrypt_buf function in library/ssl_tls.c in PolarSSL before 1.2.11 and 1.3.x before 1.3.8 allows remote attackers to cause a denial of service (crash) via vectors related to the GCM ciphersuites, as demonstrated using the Codenomicon Defensics toolkit.
