GENTOO LINUX SECURITY ANNOUNCEMENT 200303-20
- - ---------------------------------------------------------------------

          PACKAGE : openssl
          SUMMARY : Klima-Pokorny-Rosa attack
             DATE : 2003-03-24 11:51 UTC
          EXPLOIT : remote
VERSIONS AFFECTED : <0.9.6i-r2
    FIXED VERSION : >=0.9.6i-r2
              CVE : CAN-2003-0131

- - ---------------------------------------------------------------------

- From advisory:

"Czech cryptologists Vlastimil Klima, Ondrej Pokorny, and Tomas Rosa
have come up with an extension of the "Bleichenbacher attack" on RSA
with PKCS #1 v1.5 padding as used in SSL 3.0 and TLS 1.0.  Their
attack requires the attacker to open millions of SSL/TLS connections
to the server under attack; the server's behaviour when faced with
specially made-up RSA ciphertexts can reveal information that in
effect allows the attacker to perform a single RSA private key
operation on a ciphertext of its choice using the server's RSA key.
Note that the server's RSA key is not compromised in this attack."

SOLUTION

It is recommended that all Gentoo Linux users who are running
dev-libs/openssl upgrade to openssl-0.9.6i-r2 as follows:

emerge sync
emerge openssl
emerge clean
