The remote Debian host is missing a security-related update.
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.
Upgrade the linux packages. 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.
