python313-devel no longer provides python3-devel and no longer owns
libpython3.so, python3-config, python3.pc, or python3-embed.pc.
Do not package versioned GIL pkg-config files in nogil-devel. Also, fix
regular expressions in rpmlintrc.
`python3*` symbols should be now provided by real python3 packages and
its subpackages instead of the virtual provides.
Includes many small fixes:
* fixe the shebang of Tools/gdb/libpython.py to the versioned Python
* skip rpm-build-python BuildRequires for the base flavor
rpm-build-python (from python-rpm-packaging) has a runtime Requires
on python3-base. Since the base flavor is what produces python3-base,
this creates an unresolvable bootstrap cycle in OBS when the package
is not yet present in the project repo. Guard the BuildRequires with
%{without base} to break the cycle.
* explicitly provide `python(abi)` symbol
rpm-build-python (which auto-generates this) cannot be installed in
the base flavor build root due to a bootstrap cycle: rpm-build-python
-> python3-base -> (this package)

pkgutil.get_data() has the same security model as open(). The documented
limitations ensure compatibility with non-filesystem loaders; Python
doesn't check that. (bsc#1259989, CVE-2026-3479,
gh#python/cpython#146121).
- Security
- gh-144125: BytesGenerator will now refuse to serialize
(write) headers that are unsafely folded or delimited; see
verify_generated_headers. (Contributed by Bas Bloemsaat and
Petr Viktorin in gh-121650).
- gh-143935: Fixed a bug in the folding of comments when
flattening an email message using a modern email policy.
Comments consisting of a very long sequence of non-foldable
characters could trigger a forced line wrap that omitted
the required leading space on the continuation line,
causing the remainder of the comment to be interpreted as
a new header field. This enabled header injection with
carefully crafted inputs (bsc#1257029 CVE-2025-11468).
- gh-143925: Reject control characters in data: URL media
types (bsc#1257046, CVE-2025-15282).
- gh-143919: Reject control characters in http.cookies.Morsel
fields and values (bsc#1257031, CVE-2026-0672).
- gh-143916: Reject C0 control characters within
wsgiref.headers.Headers fields, values, and parameters
(bsc#1257042, CVE-2026-0865).
- gh-142145: Remove quadratic behavior in xml.minidom node ID
cache clearing. In order to do this without breaking
existing users, we also add the ownerDocument attribute to
xml.dom.minidom elements and attributes created by directly
instantiating the Element or Attr class. Note that this way
of creating nodes is not supported; creator functions like
xml.dom.Document.documentElement() should be used instead
(bsc#1254997, CVE-2025-12084).
- gh-137836: Add support of the “plaintext” element, RAWTEXT
elements “xmp”, “iframe”, “noembed” and “noframes”, and
optionally RAWTEXT element “noscript” in
html.parser.HTMLParser.
- gh-136063: email.message: ensure linear complexity for
legacy HTTP parameters parsing. Patch by Bénédikt Tran.
- gh-136065: Fix quadratic complexity in
os.path.expandvars() (bsc#1252974, CVE-2025-6075).
- gh-119451: Fix a potential memory denial of service in the
http.client module. When connecting to a malicious server,
it could cause an arbitrary amount of memory to be
allocated. This could have led to symptoms including
a MemoryError, swapping, out of memory (OOM) killed
processes or containers, or even system crashes
(CVE-2025-13836, bsc#1254400).
- gh-119452: Fix a potential memory denial of service in the
http.server module. When a malicious user is connected to
the CGI server on Windows, it could cause an arbitrary
amount of memory to be allocated. This could have led to
symptoms including a MemoryError, swapping, out of memory
(OOM) killed processes or containers, or even system
crashes.
- gh-119342: Fix a potential memory denial of service in the
plistlib module. When reading a Plist file received from
untrusted source, it could cause an arbitrary amount of
memory to be allocated. This could have led to symptoms
including a MemoryError, swapping, out of memory (OOM)
killed processes or containers, or even system crashes
(bsc#1254401, CVE-2025-13837).
- Library
- gh-144833: Fixed a use-after-free in ssl when SSL_new()
returns NULL in newPySSLSocket(). The error was reported
via a dangling pointer after the object had already been
freed.
- gh-144363: Update bundled libexpat to 2.7.4
- gh-90949: Add SetAllocTrackerActivationThreshold() and
SetAllocTrackerMaximumAmplification() to xmlparser objects
to prevent use of disproportional amounts of dynamic memory
from within an Expat parser. Patch by Bénédikt Tran.
- Core and Builtins
- gh-120384: Fix an array out of bounds crash in
list_ass_subscript, which could be invoked via some
specificly tailored input: including concurrent
modification of a list object, where one thread assigns
a slice and another clears it.
- gh-120298: Fix use-after free in list_richcompare_impl

* Vertical tabulation (\v) and non-ASCII whitespaces no longer
recognized as whitespaces. The only whitespaces are \t\n\r\f and
space.
* Null character (U+0000) no longer ends the tag name.
* Attributes and slashes after the tag name in end tags are now
ignored, instead of terminating after the first > in quoted
attribute value. E.g. </script/foo=">"/>.
* Multiple slashes and whitespaces between the last attribute and
closing > are now ignored in both start and end tags. E.g. <a
foo=bar/ //>.
* Multiple = between attribute name and value are no longer
collapsed. E.g. <a foo==bar> produces attribute “foo” with value
“=bar”.
