| From the Red Hat advisory:
A flaw allowed napi_reuse_skb() to be called on VLAN (virtual LAN)
packets. An attacker on the local network could trigger this flaw by
sending specially-crafted packets to a target system, possibly causing a
denial of service. (CVE-2011-1576)
A flaw in the way the Xen hypervisor implementation handled CPUID
instruction emulation during virtual machine exits could allow an
unprivileged guest user to crash a guest. This only affects systems that
have an Intel x86 processor with the Intel VT-x extension enabled.
(CVE-2011-1936)
A flaw in inet_diag_bc_audit() could allow a local, unprivileged user to
cause a denial of service (infinite loop). (CVE-2011-2213)
Structure padding in two structures in the Bluetooth implementation
was not initialized properly before being copied to user-space, possibly
allowing local, unprivileged users to leak kernel stack memory to
user-space. (CVE-2011-2492) |
