Vulnerabilities > CVE-2016-3634 - Out-of-bounds Read vulnerability in Libtiff
Attack vector
NETWORK Attack complexity
LOW Privileges required
NONE Confidentiality impact
NONE Integrity impact
NONE Availability impact
HIGH Summary
The tagCompare function in tif_dirinfo.c in the thumbnail tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds read) via vectors related to field_tag matching.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
