Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU21728
Risk: High
CVSSv3.1: 8.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-5050
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists in the "Page", "Kids" objects due to a boundary error when processing PDF files. A remote attacker can send a specially crafted PDF file, when opened by a victim, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.

2) Heap-based buffer overflow
EUVDB-ID: #VU21731
Risk: High
CVSSv3.1: 8.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-5045
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists in the PDF parsing functionality due to a boundary error when processing jpeg2000 files with an unusually large "ssizDepth" value in "siz" block of the code stream embedded in a PDF file. A remote attacker can send a specially crafted jpeg2000 file, when opened by a victim, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
