Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2017-2820)
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.
2) Null pointer dereference (CVE-ID: CVE-2017-7511)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to NULL pointer dereference in the 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.
3) Null pointer dereference (CVE-ID: CVE-2017-9083)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to NULL pointer dereference in the JPXStream::readUByte function in JPXStream.cc when handling malicious content. A remote attacker can send specially crafted PDF file, trick the victim into opening it, trigger segmentation fault and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
4) Memory leak (CVE-ID: CVE-2017-9406)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to memory leak in the function gmalloc in gmem.cc when handling malicious content. A remote attacker can send specially crafted file, trick the victim into opening it and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
5) Memory leak (CVE-ID: CVE-2017-9408)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to memory leak in the function Object::initArray in Object.cc when handling malicious content. A remote attacker can send specially crafted file, trick the victim into opening it and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
6) 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.
