                     CVE-2015-5707
    
    Several vulnerabilities have been discovered in the Linux kernel
    that may lead to a privilege escalation, denial of service or
    information leak.
    
    CVE-2015-1333
    
        Colin Ian King discovered a flaw in the add_key function of the
        Linux kernel's keyring subsystem. A local user can exploit this flaw
        to cause a denial of service due to memory exhaustion.
    
    CVE-2015-3212
    
        Ji Jianwen of Red Hat Engineering discovered a flaw in the handling
        of the SCTPs automatic handling of dynamic multi-homed connections.
        A local attacker could use this flaw to cause a crash or potentially
        for privilege escalation.
    
    CVE-2015-4692
    
        A NULL pointer dereference flaw was found in the
        kvm_apic_has_events function in the KVM subsystem. A unprivileged
        local user could exploit this flaw to crash the system kernel
        resulting in denial of service.
    
    CVE-2015-4700
    
        Daniel Borkmann discovered a flaw in the Linux kernel implementation
        of the Berkeley Packet Filter which can be used by a local user to
        crash the system.
    
    CVE-2015-5364
    
        It was discovered that the Linux kernel does not properly handle
        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-2015-5366
    
        It was discovered that the Linux kernel does not properly handle
        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-2015-5697
    
        A flaw was discovered in the md driver in the Linux kernel leading
        to an information leak.
    
    CVE-2015-5706
    
        An user triggerable use-after-free vulnerability in path lookup in
        the Linux kernel could potentially lead to privilege escalation.
    
    CVE-2015-5707
    
        An integer overflow in the SCSI generic driver in the Linux kernel
        was discovered. A local user with write permission on a SCSI generic
        device could potentially exploit this flaw for privilege escalation.
    
    For the oldstable distribution (wheezy), these problems have been fixed
    in version 3.2.68-1+deb7u3. CVE-2015-1333, CVE-2015-4692 and
    CVE-2015-5706 do not affect the wheezy distribution.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 3.16.7-ckt11-1+deb8u3, except CVE-2015-5364 and CVE-2015-5366
    which were fixed already in DSA-3313-1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 4.1.3-1 or earlier versions.
    
    We recommend that you upgrade your linux packages.
