Xpdf and Poppler are vulnerable to a heap overflow that may be exploited to execute arbitrary code.
| Package | app-text/xpdf on all architectures |
|---|---|
| Affected versions | < 3.01-r7 |
| Unaffected versions | >= 3.01-r7 |
| Package | app-text/poppler on all architectures |
|---|---|
| Affected versions | < 0.5.0-r4 |
| Unaffected versions | >= 0.5.0-r4 |
Xpdf is a PDF file viewer that runs under the X Window System. Poppler is a PDF rendering library based on the Xpdf 3.0 code base.
Dirk Mueller has reported a vulnerability in Xpdf. It is caused by a missing boundary check in the splash rasterizer engine when handling PDF splash images with overly large dimensions.
By sending a specially crafted PDF file to a victim, an attacker could cause an overflow, potentially resulting in the execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
All Xpdf users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.01-r7"
All Poppler users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.0-r4"
