Description

This security bulletin contains information about 3 vulnerabilities.


1) Command injection (CVE-ID: CVE-2017-1000159)

CWE-ID: CWE-77 - Command injection

CVSSv4: 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/E:U/U:Amber


The vulnerability allows a remote attacker to perform command injection attack on the target system.

The weakness exists due to an error when handling printing certain DVI files. A remote attacker can trick the victim into opening and printing a specially-named DVI file, inject arbitrary commands and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

2) Buffer overflow (CVE-ID: CVE-2019-1010006)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: 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/E:P/U:Amber


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: 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/E:U/U:Clear


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.
