Alin Rad Pop discovered several buffer overflows in the Poppler PDF library, which could allow the execution of arbitrary code if a malformed PDF file is opened.
The old stable distribution (sarge) doesn't contain poppler.
For the stable distribution (etch), these problems have been fixed in version 0.4.5-5.1etch2.
We recommend that you upgrade your poppler packages.
MD5 checksums of the listed files are available in the original advisory.
