Vulnerability Assessment Details

RHSA-2006-0661: openssl

Vulnerability Assessment Summary
Check for the version of the openssl packages

Detailed Explanation for this Vulnerability Assessment


Updated OpenSSL packages are now available to correct a security issue.

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 protocols.

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 a possible hacker 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. (CVE-2006-4339)

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.
