Description
This security bulletin contains information about 3 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2017-2814)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exist due to heap-based buffer overflow in the image rendering functionality when handling malicious data. A remote attacker can send a specially crafted PDF file, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
2) Heap-based buffer overflow (CVE-ID: CVE-2017-2818)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exist due to heap-based buffer overflow in the image rendering functionality when handling malicious data. A remote attacker can send a specially crafted PDF file, trick the victim into opening it, trigger an overly large number of color components during image rendering and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
3) Integer overflow (CVE-ID: CVE-2017-2820)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exist due to integer overflow in the JPEG 2000 image parsing functionality when handling malicious data. A remote attacker can send a specially crafted PDF file, trick the victim into opening it, trigger out of bounds memory overwrite on the heap and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
