Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Affected Versions:
linux on Debian Linux

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 Linux Distribution Packages.

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.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
