Suggested advisory:
========================

The updated package fix a security vulnerability:

Lynx before 2.8.9dev.16 is vulnerable to a use after free in the HTML parser resulting in memory disclosure, because HTML_put_string() can append a chunk onto itself. (CVE-2017-1000211)

MGA5-32 on Dell Latitude D600 Xfce
No installation issues.
Used lynx to view our own www.mageia.org, looks OK.

Updated this on Mageia 5 :: x86_64

Pointed lynx at a few sites like Mageia Bugzilla, exoplanet.eu and APOD (https://apod.nasa.gov/apod/astropix.html).  "Clicking" on the introductory text launched an image viewer with today's picture.  Clicking in this case involved down-arrow to select the field then Return to "click".  / activates the text search option.  Responding with "shadow" highlighted that word wherever it occurred in the page.  Not sure how useful that is.

It works.

Comment 5 Len Lawrence 2017-12-09 17:27:34 CET

Installed on Mageia 6 :: x86_64

Terminal-based interface working smoothly.  Visited a few sites, traversed links, displayed images and PDFs and looked at files.  No problems except with Youtube videos - always "unavailable".

OK for 64 bits.
