IBM Dynamic System Analysis (DSA) Preboot is affected by vulnerabilities in
libTIFF
Product: PureFlex System & Flex System
Component: IBM Dynamic System Analysis (DSA) Preboot
Software version: All Versions
Operating system(s): Firmware
Reference #: 0882120
Security Bulletin
Summary
IBM Dynamic System Analysis (DSA) Preboot has addressed the following
vulnerabilities in libTIFF.
Vulnerability Details
CVEID: CVE-2018-18661
DESCRIPTION: LibTIFF is vulnerable to a denial of service, caused by a NULL
pointer dereference in the LZWDecode function in tif_lzw.c. By persuading a
victim to open a specially-crafted file, a remote attacker could exploit this
vulnerability to cause a denial of service condition.
CVSS Base Score: 3.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152035 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)
CVEID: CVE-2018-12900
DESCRIPTION: LibTIFF is vulnerable to a denial of service, caused by a
heap-based buffer overflow in the cpSeparateBufToContigBuf function in
tiffcp.c. By persuading a victim to open a specially-crafted file, a remote
attacker could exploit this vulnerability to cause a denial of service
condition.
CVSS Base Score: 5.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
145464 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:H)
CVEID: CVE-2017-9147
DESCRIPTION: LibTIFF is vulnerable to a denial of service, caused by an invalid
read in the _TIFFVGetField function. By persuading a victim to open a
specially-crafted TIFF image 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/
127484 for the current score

CVEID: CVE-2017-9117
DESCRIPTION: LibTIFF is vulnerable to a heap-based buffer overflow, caused by
the processing of BMP images without verifying that biWidth and biHeight in the
bitmap-information header match the actual input. By using a specially crafted
BMP image, attacker could overflow a buffer in bmp2tiff and execute arbitrary
code on the system.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
126280 for the current score

CVEID: CVE-2017-17942
DESCRIPTION: LibTIFF is vulnerable to a heap-based buffer overflow, caused by
improper bounds checking by the function PackBitsEncode in tif_packbits.c. A
local attacker could overflow a buffer and execute arbitrary code on the
system.
CVSS Base Score: 5.9
