Advisory:
========================

Updated pdfresurrect package fixes security vulnerability:

In PDFResurrect before 0.20, lack of header validation checks causes a
heap-buffer-overflow in pdf_get_version() (CVE-2020-20740).

MGA7-64 MATE on Peaq C1011
No installation isssues.
Ref bug 26304 for test, I will upload the referredd pdf for future reference.

Remoteattacksurfaces.pdf: --A-- Version 1 -- Object 5831 (Stream)

which is similar to the previous bug report
$ pdfresurrect Remoteattacksurfaces.pdf -q
Remoteattacksurfaces.pdf: 2
no feedback at all
But 2 versions of the file heve been extracted, and can be read OK.
running the same command at a "regular" pdf file
gives similar results, but
$ pdfresurrect decl2011_43122204192.pdf -q
decl2011_43122204192.pdf: 1
only one version is present, so noadditional files created.
OK for me.
