restarted, or the system rebooted.
1.145.2. RHSA-2010:0054: Moderate security update
Important
This update has already been released (prior to the GA of this release) as the security
errata
RHSA-2010:0054
1635
Updated openssl packages that fix two security issues are now available for Red Hat Enterprise Linux
5.
This update has been rated as having moderate security impact by the Red Hat Security Response
Team.
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library.
It was found that the OpenSSL library did not properly re-initialize its internal state in the
SSL_library_init() function after previous calls to the CRYPTO_cleanup_all_ex_data() function, which
would cause a memory leak for each subsequent SSL connection. This flaw could cause server
applications that call those functions during reload, such as a combination of the Apache HTTP
Server, mod_ssl, PHP, and cURL, to consume all available memory, resulting in a denial of service.

CVE-2009-4355
1636
)
Dan Kaminsky found that browsers could accept certificates with MD2 hash signatures, even though
MD2 is no longer considered a cryptographically strong algorithm. This could make it easier for an
attacker to create a malicious certificate that would be treated as trusted by a browser. OpenSSL now
disables the use of the MD2 algorithm inside signatures by default. (
