A vulnerability has been reported in OpenSSL, which can be exploited by malicious people to potentially compromise an application using the library.
The vulnerability is caused due to an error when handling CMS (Cryptographic Message Syntax) structures. This can be exploited to trigger a write to an invalid memory address or a double-free via a specially crafted CMS structure containing an "OriginatorInfo" element.
Successful exploitation may allow execution of arbitrary code, but requires that CMS is enabled (disabled by default in 0.9.x).
The vulnerability is reported in versions 0.9.8h and later.
Solution: Update to version 0.9.8o.
Provided and/or discovered by: The vendor credits Ronald Moesbergen.
