Description

From Red Hat Security Advisory 2017:2551 :

An update for poppler is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Poppler is a Portable Document Format (PDF) rendering library, used by applications such as Evince.

Security Fix(es) :

  • A stack-based buffer overflow was found in the poppler library. An attacker could create a malicious PDF file that would cause applications that use poppler (such as Evince) to crash, or potentially execute arbitrary code when opened. (CVE-2017-9775)

  • An integer overflow leading to heap-based buffer overflow was found in the poppler library. An attacker could create a malicious PDF file that would cause applications that use poppler (such as Evince) to crash, or potentially execute arbitrary code when opened. (CVE-2017-9776)
