Description

This security bulletin contains information about 1 vulnerability.


1) Buffer overflow (CVE-ID: CVE-2017-7593)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to gain access to sensitive information.

tif_read.c in LibTIFF 4.0.7 does not ensure that tif_rawdata is properly initialized, which might allow remote attackers to obtain sensitive information from process memory via a crafted image.
