CVE-2017-9233

Published: 21 June 2017

XML External Entity vulnerability in libexpat 2.2.0 and earlier (Expat XML Parser Library) allows attackers to put the parser in an infinite loop using a malformed external entity definition from an external DTD.

Notes

AuthorNote
mdeslaur
we will not be fixing this in thunderbird, marking as ignored
rodrigo-zaiden
libxmltok does not include entityValueInitProcessor function.
so, it's not affected.
ccdm94
cmake 3.20.5 and forward uses expat 2.2.10+.
