Description
This security bulletin contains information about 3 vulnerabilities.
1) Improper Neutralization of Argument Delimiters in a Command (CVE-ID: CVE-2026-46529)
CWE-ID: CWE-88 - Argument Injection or Modification
CVSSv4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to improper neutralization of argument delimiters in a command in ev_spawn() in shell/ev-application.c when processing a crafted /GoToR action in a PDF document. A remote attacker can trick the victim into clicking a crafted link in a malicious PDF to execute arbitrary code.
User interaction is required to click a link inside the PDF document, and the issue can be delivered as a single polyglot file that is both a valid PDF and a valid ELF shared library.
2) Buffer overflow (CVE-ID: CVE-2019-1010006)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code or cause a denial of service (DoS) condition on a targeted system.
The vulnerability exists due to a buffer overflow condition in the "backend/tiff/tiff-document.c" when handling PDF files. A remote attacker can trick a victim to open a specially crafted PDF file and execute arbitrary code or cause a DoS condition on the targeted system.
3) Access of Uninitialized Pointer (CVE-ID: CVE-2019-11459)
CWE-ID: CWE-824 - Access of Uninitialized Pointer
CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due tothe TIFFReadRGBAImageOriented() function called from tiff_document_render() and tiff_document_get_thumbnail() functions in the backend/tiff/tiff-document.c in GNOME Evince returns uninitialized memory instead of false, when failing to read an image. A remote attacker can gain access to sensitive information on the system.
