Description

This update for mupdf to version 1.12.0 fixes several issues.

These security issues were fixed :

  • CVE-2018-5686: Prevent infinite loop in pdf_parse_array function because EOF is not considered. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted pdf file (bsc#1075936).

  • CVE-2017-15369: The build_filter_chain function in pdf/pdf-stream.c mishandled a case where a variable may reside in a register, which allowed remote attackers to cause a denial of service (Fitz fz_drop_imp use-after-free and application crash) or possibly have unspecified other impact via a crafted PDF document (bsc#1063413).

  • CVE-2017-15587: Prevent integer overflow in pdf_read_new_xref_section that allowed for DoS (bsc#1064027).

  • CVE-2017-17866: Fixed mishandling of length changes when a repair operation occured during a clean operation, which allowed remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted PDF document (bsc#1074116).

  • CVE-2017-17858: Fixed a heap-based buffer overflow in the ensure_solid_xref function which allowed a remote attacker to potentially execute arbitrary code via a crafted PDF file, because xref subsection object numbers were unrestricted (bsc#1077161).

For non-security changes please refer to the changelog.
