A cache-based side channel in GnuTLS implementation that leads to plain text recovery in cross-VM attack setting was found. An attacker could use a combination of "Just in Time" Prime+probe attack in combination with Lucky-13 attack to recover plain text using crafted packets.
A cache-based side channel attack was found in the way GnuTLS implements CBC-mode cipher suites. An attacker could use a combination of "Just in Time" Prime+probe and Lucky-13 attacks to recover plain text in a cross-VM attack scenario.
