Description Gianluca Gabrielli 2024-07-12 08:32:05 UTC 
+++ This bug was initially created as a clone of Bug #1227687 +++

The polyfill.js is a popular open source library to support older browsers. 100K+ sites embed it using the cdn.polyfill.io domain. Notable users are JSTOR, Intuit and World Economic Forum. However, in February this year, a Chinese company bought the domain and the Github account. Since then, this domain was caught injecting malware on mobile devices via any site that embeds cdn.polyfill.io.

Comment 1 Gianluca Gabrielli 2024-07-12 08:42:28 UTC 
The following packages loads data from polyfill.io in doc/pamhomography.html

 - SUSE:ALP:Source:Standard:1.0/netpbm
 - openSUSE:Factory/netpbm
 - SUSE:SLFO:Main/netpbm

I'm not sure how/if the upstream fixed it, but you can simply replace the malicious domain with https://cdnjs.cloudflare.com.

The following packages are not affected

 - SUSE:SLE-12:Update/netpbm
 - SUSE:SLE-15:Update/netpbm

I have notified upstream author Bryan Henderson (bryanh@giraffe-data.com).
