Description

This security bulletin contains information about 2 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2013-1929)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 5.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the tg3_read_vpd function in drivers/net/ethernet/broadcom/tg3.c in the Linux kernel before 3.8.6. A remote attacker can use crafted firmware that specifies a long string in the Vital Product Data to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) NULL pointer dereference (CVE-ID: CVE-2013-3301)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to execute arbitrary code.

The ftrace implementation in the Linux kernel before 3.8.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for write access to the (1) set_ftrace_pid or (2) set_graph_function file, and then making an lseek system call.
