USN-884-1: OpenSSL vulnerability

Releases

• Ubuntu 9.10
• Ubuntu 9.04
• Ubuntu 8.10
• Ubuntu 8.04
• Ubuntu 6.06

Packages

• openssl -

Details

It was discovered that OpenSSL did not correctly free unused memory in
certain situations. A remote attacker could trigger this flaw in services
that used SSL, causing the service to use all available system memory,
leading to a denial of service.

Update instructions

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

Ubuntu 9.10

• libssl0.9.8 - 0.9.8g-16ubuntu3.1

Ubuntu 9.04

• libssl0.9.8 - 0.9.8g-15ubuntu3.4

Ubuntu 8.10

• libssl0.9.8 - 0.9.8g-10.1ubuntu2.6

Ubuntu 8.04

• libssl0.9.8 - 0.9.8g-4ubuntu3.9

Ubuntu 6.06

• libssl0.9.8 - 0.9.8a-7ubuntu0.11

After a standard system upgrade you need to restart any applications
using OpenSSL, especially Apache, to effect the necessary changes.
