14 DAY TRIAL // Canonical published details about poppler vulnerabilities in a security notice for its Ubuntu 12.10, Ubuntu 12.04 LTS, Ubuntu 11.10, Ubuntu 10.04 LTS, and Ubuntu 8.04 LTS operating systems.
According to Canonical, applications using poppler could be made to crash or possibly run programs as your login if they opened a specially crafted file.
It was discovered that poppler contained multiple security issues when parsing malformed PDF documents.
If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or possibly execute arbitrary code, with privileges of the user invoking the program.
For a more detailed description of the security problems, you can visit Canonical's security notification.
The security flaws can be fixed if you upgrade your system(s) to the latest libpoppler-glib8 and libpoppler28 package, specific to each distribution. To apply the update, run the Update Manager application.
In general, a standard system update will make all the necessary changes. A system restart will not be needed to implement the changes.
