Ubuntu Security Notice 1387-1 - Aristide Fattori and Roberto Paleari reported a flaw in the Linux kernel's handling of IPv4 icmp packets. A remote user could exploit this to cause a denial of service. A flaw was found in the Linux Ethernet bridge's handling of IGMP (Internet Group Management Protocol) packets. An unprivileged local user could exploit this flaw to crash the system. Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local user who can mount a FUSE file system could cause a denial of service. Various other issues were also addressed.

A local, unprivileged could exploit this flaw to cause a denial of service. A flaw was discovered in the TOMOYO LSM's handling of mount system calls. An unprivileged user could oops the system causing a denial of service. Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local user who can mount a FUSE file system could cause a denial of service. Various other issues were also addressed.

A local user who can mount a FUSE file system could cause a denial of service. A flaw was found in KVM's Programmable Interval Timer (PIT). When a virtual interrupt control is not available a local user could use this to cause a denial of service by starting a timer. A flaw was discovered in the XFS filesystem. If a local user mounts a specially crafted XFS image it could potential execute arbitrary code on the system. Various other issues were also addressed.

A local, unprivileged user could read the results of a previous TPM command. Clement Lecigne discovered a bug in the HFS filesystem. A local attacker could exploit this to cause a kernel oops. Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local user who can mount a FUSE file system could cause a denial of service. Various other issues were also addressed.
b1e4fd303c32ef48c4707df2951a82c4d83d018bba184fef1cde1f4a96af3ce5Red Hat Security Advisory 2012-0010-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A malicious CIFS server could send a specially-crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted. The way fragmented IPv6 UDP datagrams over the bridge with UDP Fragmentation Offload functionality on were handled could allow a remote attacker to cause a denial of service.

IPv6 fragment identification value generation could allow a remote attacker to disrupt a target system's networking, preventing legitimate users from accessing its services. A signedness issue was found in the Linux kernel's CIFS implementation. A malicious CIFS server could send a specially-crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted.
