Summary

pdf/pdf-write.c in Artifex MuPDF before 1.12.0 mishandles certain length changes when a repair operation occurs during a clean operation, which allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted PDF document.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionThis 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.
