Description
This security bulletin contains information about 1 vulnerability.
1) Heap-based buffer overread (CVE-ID: CVE-2017-14733)
CWE-ID: CWE-126 - Buffer over-read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to ReadRLEImage in coders/rle.c mishandles RLE headers that specify too few colors. A remote attacker can provide a specially crafted RLE document, trigger heap-based buffer over-read and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
