A buffer underflow vulnerability and an information disclosure vulnerability have been discovered in OpenSSL.
OpenSSL is an implementation of the Secure Socket Layer and Transport Layer Security protocols.
Moritz Jodeit reported an off-by-one error in the SSL_get_shared_ciphers() function, resulting from an incomplete fix of CVE-2006-3738. A flaw has also been reported in the BN_from_montgomery() function in crypto/bn/bn_mont.c when performing Montgomery multiplication.
A remote attacker sending a specially crafted packet to an application relying on OpenSSL could possibly execute arbitrary code with the privileges of the user running the application. A local attacker could perform a side channel attack to retrieve the RSA private keys.
There is no known workaround at this time.
All OpenSSL users should upgrade to the latest version:
