[USN-2681-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 9
CVEs 6
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

A flaw was discovered in the user space memory copying for the pipe iovecs
in the Linux kernel. An unprivileged local user could exploit this flaw to
cause a denial of service (system crash) or potentially escalate their
privileges. (CVE-2015-1805)

A flaw was discovered in the kvm (kernel virtual machine) subsystem's
kvm_apic_has_events function. A unprivileged local user could exploit this
flaw to cause a denial of service (system crash). (CVE-2015-4692)

Daniel Borkmann reported a kernel crash in the Linux kernel's BPF filter
JIT optimization. A local attacker could exploit this flaw to cause a
denial of service (system crash). (CVE-2015-4700)

A flaw was discovered in how the Linux kernel handles invalid UDP
checksums. A remote attacker could exploit this flaw to cause a denial of
service using a flood of UDP packets with invalid checksums.
(CVE-2015-5364)

A flaw was discovered in how the Linux kernel handles invalid UDP
checksums. A remote attacker can cause a denial of service against
applications that use epoll by injecting a single packet with an invalid
checksum. (CVE-2015-5366)

A double free flaw was discovered in the Linux kernel's path lookup. A
local user could cause a denial of service (Oops). (CVE-2015-5706)
