Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Out-of-bounds read (CVE-ID: CVE-2019-10871)

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 PSOutputDev::checkPageSlice in PSOutputDev.cc. A remote attacker can perform a denial of service attack.

2) Out-of-bounds read (CVE-ID: CVE-2019-10872)

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 Splash::blitTransparent in splash/Splash.cc. A remote attacker can perform a denial of service attack.

3) NULL pointer dereference (CVE-ID: CVE-2019-10873)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dreference error in function SplashClip::clipAALine in splash/SplashClip.cc. A remote attacker can perform a denial of service (DoS) attack.

4) Out-of-bounds read (CVE-ID: CVE-2019-9631)

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 CairoRescaleBox.cc downsample_row_box_filter function. A remote attacker can perform a denial of service attack.

5) Buffer overflow (CVE-ID: CVE-2019-9543)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in JBIG2Stream::readGenericBitmap() function in JBIG2Stream.cc. A remote attacker can create a specially crafted PDF file and crash the affected application.

6) Buffer overflow (CVE-ID: CVE-2019-9545)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing PDF files within the JBIG2Stream::readTextRegion() function in JBIG2Stream.cc. A remote attacker can create a specially crafted PDF document, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

7) Heap-based buffer overflow (CVE-ID: CVE-2019-9200)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing PDF files in ImageStream::getLine() function in Stream.cc. A remote 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.
