The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-0051 advisory.
- Resolves: bz#772079 (EMBARGOED CVE-2012-0029 qemu-kvm: e1000: process_tx_desc legacy mode packets heap overflow [rhel-5.7.z])
- Resolves: bz#770100 (CVE-2011-4622 kernel: kvm: pit timer with no irqchip crashes the system [rhel-5.7.z])
Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
