Subject: [PATCH] [CVE-2023-27043] gh-102988: Reject malformed addresses in
|
||||||
|
email.parseaddr() (#111116)
|
||||||
|
|
||||||
|
Detect email address parsing errors and return empty tuple to
|
||||||
|
indicate the parsing error (old API). Add an optional 'strict'
|
||||||
|
parameter to getaddresses() and parseaddr() functions. Patch by
|
||||||
|
Thomas Dwyer.

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)
