Package : pypy3
Version : 7.3.5+dfsg-2+deb11u3
CVE ID : CVE-2023-6597 CVE-2023-24329 CVE-2023-40217 CVE-2024-0450
Debian Bug :
Brief introduction
CVE-2023-6597
An issue was found in the CPython `tempfile.TemporaryDirectory` class
affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and
prior. The tempfile.TemporaryDirectory class would dereference
symlinks during cleanup of permissions-related errors. This means
users which can run privileged programs are potentially able to modify
permissions of files referenced by symlinks in some circumstances.
CVE-2023-24329
An issue in the urllib.parse component of Python before 3.11.4 allows
attackers to bypass blocklisting methods by supplying a URL that starts
with blank characters.
CVE-2023-40217
An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18,
3.10.x before 3.10.13, and 3.11.x before 3.11.5. It primarily affects
servers (such as HTTP servers) that use TLS client authentication. If
a TLS server-side socket is created, receives data into the socket
buffer, and then is closed quickly, there is a brief window where
the SSLSocket instance will detect the socket as "not connected" and
won't initiate a handshake, but buffered data will still be readable
from the socket buffer. This data will not be authenticated if the
server-side TLS peer is expecting client certificate authentication,
and is indistinguishable from valid TLS stream data. Data is limited
in size to the amount that will fit in the buffer. (The TLS connection
cannot directly be used for data exfiltration because the vulnerable
code path requires that the connection be closed on initialization
of the SSLSocket.)
CVE-2024-0450
An issue was found in the CPython `zipfile` module affecting versions
3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The zipfile
module is vulnerable to “quoted-overlap” zip-bombs which exploit
the zip format to create a zip-bomb with a high compression ratio. The
fixed versions of CPython makes the zipfile module reject zip archives
which overlap entries in the archive.
For Debian 11 bullseye, these problems have been fixed in version
7.3.5+dfsg-2+deb11u3.
We recommend that you upgrade your pypy3 packages.

ELA-1230-1 context bugfix update
Package : context
Version : 2018.04.04.20181118-1+deb10u1 (buster)
The CVE-2023-32700 fix for the texlive-bin package, released for Debian 10
“buster” as DLA-3427-1, introduced a regression in context, a general-purpose
document processor. The DLA-3427-1 update broke the context binary package
installation process.
This regression update corrects the issue, fixing the context package’s mtxrun script
