Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Stack-based buffer overflow
EUVDB-ID: #VU7270
Risk: High
CVSSv4.0: 5.7 [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]
CVE-ID: CVE-2017-9775
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when processing PDF files within GfxState.cc in pdftocairo in Poppler before 0.56. A remote unauthenticated attacker can create a specially crafted PDF file, trick the victim into opening it, trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package poppler to version 0.56.0-1.

EUVDB-ID: #VU7272
Risk: High
CVSSv4.0: 5.7 [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]
CVE-ID: CVE-2017-9776
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow when processing PDF files within JBIG2Stream.cc in pdftocairo in Poppler before 0.56. A remote unauthenticated attacker can create a specially crafted PDF file, trick the victim into opening it, 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.
MitigationUpdate the affected package poppler to version 0.56.0-1.
