Details

Neel Mehta discovered that incorrectly formatted ClientHello handshake
messages could cause OpenSSL to parse past the end of the message.
This could allow a remote attacker to cause a crash and denial of
service by triggering invalid memory accesses.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 10.10

• libssl0.9.8 - 0.9.8o-1ubuntu4.4

Ubuntu 10.04

• libssl0.9.8 - 0.9.8k-7ubuntu8.6

After a standard system update you need to reboot your computer to make
all the necessary changes.
