SynopsisThe remote Debian host is missing a security-related update.
DescriptionNeel Mehta discovered that an incorrectly formatted ClientHello handshake message could cause OpenSSL to parse past the end of the message. This allows an attacker to crash an application using OpenSSL by triggering an invalid memory access. Additionally, some applications may be vulnerable to expose contents of a parsed OCSP nonce extension.
Packages in the oldstable distribution (lenny) are not affected by this problem.
SolutionUpgrade the openssl packages.
For the stable distribution (squeeze), this problem has been fixed in version 0.9.8o-4squeeze1.
