OpenSSL: Multiple vulnerabilities

OpenSSL: Multiple vulnerabilities A buffer underflow vulnerability and an information disclosure vulnerability have been discovered in OpenSSL. openssl October 07, 2007 October 07, 2007: 01 188799 194039 local, remote 0.9.8e-r3 0.9.8e-r3

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:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8e-r3"
