Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Uncontrolled recursion (CVE-ID: CVE-2017-7515)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to uncontrolled recursion in pdfunite when handling malicious content. A remote attacker can send specially crafted PDF file, trick the victim into opening it and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
2) Stack-based buffer overflow (CVE-ID: CVE-2017-9775)
The 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.
3) Integer overflow (CVE-ID: CVE-2017-9776)
The 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.
4) Buffer over-read (CVE-ID: CVE-2017-9865)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in The function GfxImageColorMap::getGray in GfxState.cc in Poppler 0.54.0. A remote attacker can perform a denial of service (stack-based buffer over-read and application crash) via a specially crafted PDF document, related to missing color-map validation in ImageOutputDev.cc.
