Summary

Multiple vulnerabilities have been identified in freetype2 that is embedded in the FSM. This bulletin addresses these vulnerabilities.

Vulnerability Details

CVEID: CVE-2017-8287**
DESCRIPTION:** Freetype2 is vulnerable to a denial of service, caused by a heap-based buffer overflow in the t1_builder_close_contour function in psaux/psobjs.c. An attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 6.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/125406 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2017-8105**
DESCRIPTION:** Freetype 2 is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the t1_decoder_parse_charstrings function in psaux/t1decode.c. A local attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/125262 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2016-10244**
DESCRIPTION:** Freetype is vulnerable to a denial of service, caused by heap-based buffer overflow in the parse_charstrings function in type1/t1load.c. By persuading a victim to open a a crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 3.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/124256 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)

1.3.2.1
1.3.2.2
1.3.2.3 Navigate to the Support Portal_ _and search for technote 847550927 for instructions on installing updates for FSM version 1.3.2 and Agents.

For all other VRMF IBM recommends upgrading to a fixed, supported version/release of the product.

Note: Installation of the fixes provided in the technote will install a cumulative fix package that will update the version of the FSM. Reference the technote for more details.

You should verify applying this fix does not cause any compatibility issues. The fix may disable older encrypted protocols by default.

IBM recommends that you review your entire environment to identify other areas where you have enabled weak encryption and take appropriate mitigation and remediation actions.
