========================================================================== Ubuntu Security Notice USN-1428-1 April 24, 2012
openssl vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS
Summary:
An application using OpenSSL could be made to crash or run programs if it opened a specially crafted file.
Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools
Details:
It was discovered that the fix for CVE-2012-2110 was incomplete for OpenSSL 0.9.8. A remote attacker could trigger this flaw in services that used SSL to cause a denial of service or possibly execute arbitrary code with application privileges. Ubuntu 11.10 was not affected by this issue. (CVE-2012-2131)
The original upstream fix for CVE-2012-2110 would cause BUF_MEM_grow_clean() to sometimes return the wrong error condition. This update fixes the problem.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.10: libssl1.0.0 1.0.0e-2ubuntu4.5
Ubuntu 11.04: libssl0.9.8 0.9.8o-5ubuntu1.5
Ubuntu 10.04 LTS: libssl0.9.8 0.9.8k-7ubuntu8.11
Ubuntu 8.04 LTS: libssl0.9.8 0.9.8g-4ubuntu3.18
After a standard system update you need to reboot your computer to make all the necessary changes.
