Security Bulletin: IBM Dynamic System Analysis (DSA) Preboot is affected by vulnerabilities in libTIFF

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.

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.
