Description
This security bulletin contains information about 1 vulnerability.
1) Out-of-bounds write (CVE-ID: CVE-2017-11335)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists in the ZIPDecode function in tif_zip.c in tools/tiff2pdf.c due to heap-based buffer overflow. A remote attacker can trick the victim into opening a specially crafted PlanarConfig=Contig image, trigger a more than one hundred bytes out-of-bounds write and cause the service to crash or execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
