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)

According to the versions of the poppler packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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)

Poppler developers report :

Poppler is prone to a stack-based buffer-overflow vulnerability.

Successful exploits may allow attackers to crash the affected application, resulting in denial-of-service condition. Due to the nature of this issue, arbitrary code execution may be possible but this has not been confirmed.
