sol15329: SSL_MODE_RELEASE_BUFFERS vulnerability CVE-2014-0198 Security 
AdvisorySecurity Advisory

Original Publication Date: 06/13/2014

Description

The do_ssl3_write function in s3_pkt.c in OpenSSL 1.x through 1.0.1g, when 
SSL_MODE_RELEASE_BUFFERS is enabled, does not properly manage a buffer pointer
during certain recursive calls, which allows remote attackers to cause a 
denial of service (NULL pointer dereference and application crash) via vectors
that trigger an alert condition. (CVE-2014-0198)

Impact

A remote attacker could cause a denial-of-service (DoS).
