Comment 1 Nicolas Salguero 2021-11-12 09:21:04 CET

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

The updated packages fix a security vulnerability:

TinyXML through 2.6.2 has an infinite loop in TiXmlParsingData::Stamp in tinyxmlparser.cpp via the TIXML_UTF_LEAD_0 case. It can be triggered by a crafted XML message and leads to a denial of service. (CVE-2021-42260)

Comment 2 Herman Viaene 2021-11-12 16:32:50 CET

MGA8-64 Plasma on Lenovo B50
No installation issues.
No wiki, no previous updates, so run:
# urpmq --whatrequires lib64tinyxml0
and got some 35 answers, picked one I thought I might understand and run:
$ strace -o libtinyxml.txt pokerth 
I must admit I don't get it at all, but I run it as one user, pushed some buttons to which the application reacted, and in the trace I see one call to 
/lib64/libtinyxml.so.0
Good enough for me, unless someone else has better ideas.
