Description

This security bulletin contains information about 2 vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2016-10147)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to NULL pointer dereference within the mcryptd_check_internal() and mcryptd_create_hash() functions in crypto/mcryptd.c. A local user can perform a denial of service (DoS) attack.


2) Stack-based buffer overflow (CVE-ID: CVE-2016-8399)

CWE-ID: CWE-121 - Stack-based buffer overflow

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 cause kernel panic or escalate privileges.

The vulnerability exists due to a boundary error when crating an ICMP header. A local user can create a very short ICMP header and execute arbitrary code within the contest of the kernel.

Successful exploitation of the vulnerability may allow a local user to escalate privileges on the system.
