Description
This security bulletin contains information about 3 vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2017-14314)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/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 th etarget system.
The weakness exists in the DrawImage function in magick/render.c due to off-by-one error. A remote attacker can trick the victim into opening a specially crafted file, trigger heap-based buffer over-read and cause the service to crash.
2) Heap-based buffer overflow (CVE-ID: CVE-2017-16352)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 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/E:P/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the "Display visual image directory" feature of the DescribeImage() function of the magick/describe.c file due to heap-based buffer overflow. A remote attacker can trick the victim into opening a specially crafted MIFF format file with the verbose flag, trigger memory corruption and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
3) Memory corruption (CVE-ID: CVE-2017-16353)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists in the DescribeImage function of the magick/describe.c file due to heap-based buffer over-read because the portion of the code containing the vulnerability is responsible for printing the IPTC Profile information contained in the image and out-of-bounds buffer dereference because certain increments are never checked. A remote attacker can trick the victim into opening a specially crafted MIFF file and gain access to potentially sensitive information.
