Description

libssh before 0.7.3 improperly truncates ephemeral secrets generated for the (1) diffie-hellman-group1 and (2) diffie-hellman-group14 key exchange methods to 128 bits, which makes it easier for man-in-the-middle attackers to decrypt or intercept SSH sessions via unspecified vectors, aka a "bits/bytes confusion bug."

Solution(s)

  • gentoo-linux-upgrade-net-libs-libssh
  • gentoo-linux-upgrade-net-libs-libssh2
