Summary
Red Hat Security Advisory: apache, openssl security update for Stronghold

Notes

Topic
Updated versions of cross-platform Stronghold 4 are available to fix a number of vulnerabilities in OpenSSL and Apache.
Details
Stronghold 4 contains various open source technologies such as OpenSSL and Apache. A number of issues have been found in versions of these projects: Researchers discovered a timing attack on RSA keys that affects OpenSSL. A local or remote attacker could use this attack to obtain the server's private key by determining factors using timing differences on (1) the number of extra reductions during Montgomery reduction and (2) the use of different integer multiplication algorithms (Karatsuba and normal). Stronghold does not enable RSA blinding by default and is, therefore, vulnerable to this attack. The SSL and TLS components for OpenSSL allow remote attackers to perform an unauthorized RSA private key operation via a modified Bleichenbacher attack. This attack (also known as the Klima-Pokorny-Rosa attack) uses a large number of SSL or TLS connections, using PKCS #1 v1.5 padding, and causes OpenSSL to leak information regarding the relationship between ciphertext and the associated plaintext. Versions of Apache 1.3 before 1.3.25 do not filter terminal escape sequences from access logs, which could make it easier for attackers to insert those sequences into terminal emulators containing vulnerabilities related to escape sequences. These erratum packages contain a patch provided by the OpenSSL group that enables RSA blinding by default, thereby protecting against the Klima-Pokorny-Rosa attack, and a patch to filter escape sequences from Apache access logs.
