The remote Red Hat host is missing one or more security updates.
Updated OpenSSL packages are now available to correct a security
This update has been rated as having important security impact by the
Red Hat Security Response Team.
The OpenSSL toolkit provides support for secure communications between
machines. OpenSSL includes a certificate management tool and shared
libraries which provide various cryptographic algorithms and
Daniel Bleichenbacher recently described an attack on PKCS #1 v1.5
signatures. Where an RSA key with exponent 3 is used it may be
possible for an attacker to forge a PKCS #1 v1.5 signature that would
be incorrectly verified by implementations that do not check for
excess data in the RSA exponentiation result of the signature.
The Google Security Team discovered that OpenSSL is vulnerable to this
attack. This issue affects applications that use OpenSSL to verify
X.509 certificates as well as other uses of PKCS #1 v1.5.
This errata also resolves a problem where a customized ca-bundle.crt
file was overwritten when the openssl package was upgraded.
Users are advised to upgrade to these updated packages, which contain
a backported patch to correct this issue.
Note: After installing this update, users are advised to either
restart all services that use OpenSSL or restart their system.
