All supported architectures
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
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:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8e-r3"
