Subject: [PATCH] gh-115133: Fix tests for XMLPullParser with Expat 2.6.0
|
||||
(GH-115164)
|
||||
|
||||
Feeding the parser by too small chunks defers parsing to prevent
|
||||
CVE-2023-52425. Future versions of Expat may be more reactive.
|
||||
(cherry picked from commit 4a08e7b3431cd32a0daf22a33421cd3035343dc4)
