Details
It was discovered that OpenSSL incorrectly handled return codes from the
bn_wexpand function calls. 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. This issue only affected Ubuntu
6.06 LTS, 8.04 LTS, 9.04 and 9.10. (CVE-2009-3245)
It was discovered that OpenSSL incorrectly handled certain private keys
with an invalid prime. 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. The default compiler options
for affected releases should reduce the vulnerability to a denial of
service. (CVE-2010-2939)
