Description

This security bulletin contains information about 2 vulnerabilities.


1) Memory leak (CVE-ID: CVE-2013-4205)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: 6.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within the unshare_userns function in kernel/user_namespace.c in the Linux kernel before 3.10.6 allows local users to cause a denial of service (memory consumption) via an invalid CLONE_NEWUSER unshare call. A remote attacker can perform a denial of service attack.


2) NULL pointer dereference (CVE-ID: CVE-2013-4254)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 8.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in arch/arm/kernel/perf_event.c in the Linux kernel before 3.10.8 on the ARM platform allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) by adding a hardware event to an event group led by a software event. A remote attacker can perform a denial of service (DoS) attack.
