pdftohtml is a utility to convert PDF files to HTML or XML formats. It makes use of Xpdf code to decode PDF files.
Xpdf is vulnerable to multiple integer overflows, as described in GLSA 200410-20.
An attacker could entice a user to convert a specially-crafted PDF file, potentially resulting in execution of arbitrary code with the rights of the user running pdftohtml.
There is no known workaround at this time.
All pdftohtml users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/pdftohtml-0.36-r1"
