Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2019-12515)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the function FlateStream::getChar() located at Stream.cc. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
2) Out-of-bounds read (CVE-ID: CVE-2019-12493)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the PostScriptFunction::transform() function in Function.cc. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger stack-based out-of-bounds read error and crash the application.
3) Out-of-bounds read (CVE-ID: CVE-2019-12957)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the FoFiType1C::convertToType1() function in fofi/FoFiType1C.cc. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger out-of-bounds read error and crash the application.
4) Out-of-bounds read (CVE-ID: CVE-2019-12958)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the FoFiType1C::convertToType0() function in fofi/FoFiType1C.cc. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger out-of-bounds read error and crash the application.
5) Out-of-bounds read (CVE-ID: CVE-2019-13283)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the FoFiType1::parse() function in fofi/FoFiType1.cc, when processing PDF files. A remote attacker can perform a denial of service attack.
6) Out-of-bounds read (CVE-ID: CVE-2019-13282)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the SampledFunction::transform() function in Function.cc. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger out-of-bounds read error and crash the application.
7) Heap-based buffer overflow (CVE-ID: CVE-2019-13281)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the DCTStream::decodeImage() function in Stream.cc. A remote attacker can create a specially crafted PDF file, 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.
8) Out-of-bounds read (CVE-ID: CVE-2019-13286)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in the function JBIG2Stream::readTextRegionSeg() located at JBIG2Stream.cc. A remote attacker can perform a denial of service attack.
