Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Infinite loop (CVE-ID: CVE-2018-19777)

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

The vulnerability exists due to infinite loop within the svg_dev_end_tile in fitz/svg-device.c, as demonstrated by mutool. A remote attacker can consume all available system resources and trigger denial of service condition.


2) Heap-based buffer overflow (CVE-ID: CVE-2019-13290)

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

The vulnerability exists due to a boundary error within the fz_append_display_node located at fitz/list-device.c, allowing remote attackers to execute arbitrary code via a crafted PDF file with a large BDC property name that overflows the allocated size of a display list node. A remote attacker can create a specially crafted 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.
