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.
