Insight

Insight

Neel 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. For the stable distribution (squeeze), this problem has been fixed in version 0.9.8o-4squeeze1. For the testing distribution (wheezy), this problem has been fixed in version 0.9.8o-5. For the unstable distribution (sid), this problem has been fixed in version 0.9.8o-5.

Solution

Solution

We recommend that you upgrade your invalid memory access packages.
