GLSA-200609-05 : OpenSSL, AMD64 x86 emulation base libraries: RSA signature forgery

medium Nessus Plugin ID 22327

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200609-05 (OpenSSL, AMD64 x86 emulation base libraries: RSA signature forgery)

Daniel Bleichenbacher discovered that it might be possible to forge signatures signed by RSA keys with the exponent of 3.
Impact :

Since several CAs are using an exponent of 3 it might be possible for an attacker to create a key with a false CA signature.
Workaround :

There is no known workaround at this time.

Solution

All OpenSSL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/openssl-0.9.7k' All AMD64 x86 emulation base libraries users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-emulation/emul-linux-x86-baselibs-2.5.2'
