GLSA-200806-08 : OpenSSL: Denial of Service
Medium Nessus Plugin ID 33244
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200806-08 (OpenSSL: Denial of Service)
Ossi Herrala and Jukka Taimisto of Codenomicon discovered two vulnerabilities:
A double free() call in the TLS server name extension (CVE-2008-0891).
The OpenSSL client code does not properly handle servers that omit the Server Key Exchange message in the TLS handshake (CVE-2008-1672).
A remote attacker could connect to a vulnerable server, or entice a daemon to connect to a malicious server, causing a Denial of Service of the daemon in both cases.
There is no known workaround at this time.
SolutionAll OpenSSL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/openssl-0.9.8g-r2'
