[GLSA-200601-17] Xpdf, Poppler, GPdf, libextractor, pdftohtml: Heap overflows

Vulnerability Assessment Summary
Xpdf, Poppler, GPdf, libextractor, pdftohtml: Heap overflows

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200601-17
(Xpdf, Poppler, GPdf, libextractor, pdftohtml: Heap overflows)

Chris Evans has reported some integer overflows in Xpdf when
attempting to calculate buffer sizes for memory allocation, leading to
a heap overflow and a potential infinite loop when handling malformed
input files.

Impact

By sending a specially crafted PDF file to a victim, a possible hacker
could cause an overflow, potentially resulting in the execution of
arbitrary code with the rights of the user running the application.

Workaround

There is no known workaround at this time.
