Details

It was discovered that OpenSSL did not properly validate the length of an
encoded BMPString or UniversalString when printing ASN.1 strings. If a user
or automated system were tricked into processing a crafted certificate, an
attacker could cause a denial of service via application crash in
applications linked against OpenSSL.

Update instructions

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

Ubuntu 8.10

• libssl0.9.8 - 0.9.8g-10.1ubuntu2.2

Ubuntu 8.04

• libssl0.9.8 - 0.9.8g-4ubuntu3.5

Ubuntu 7.10

• libssl0.9.8 - 0.9.8e-5ubuntu3.4

Ubuntu 6.06

• libssl0.9.8 - 0.9.8a-7ubuntu0.7

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
