kernel did not properly check for the device to be enabled before
writing. A local attacker could possibly use this to cause a denial of
service. (CVE-2024-25741)

USN-7117-1: needrestart and Module::ScanDeps vulnerabilities

Read Time:48 Second

Qualys discovered that needrestart passed unsanitized data to a library
(libmodule-scandeps-perl) which expects safe input. A local attacker could
possibly use this issue to execute arbitrary code as root.
(CVE-2024-11003)

Qualys discovered that the library libmodule-scandeps-perl incorrectly
parsed perl code. This could allow a local attacker to execute arbitrary
shell commands. (CVE-2024-10224)

Qualys discovered that needrestart incorrectly used the PYTHONPATH
environment variable to spawn a new Python interpreter. A local attacker
could possibly use this issue to execute arbitrary code as root.
(CVE-2024-48990)

Qualys discovered that needrestart incorrectly checked the path to the
Python interpreter. A local attacker could possibly use this issue to win
a race condition and execute arbitrary code as root. (CVE-2024-48991)

Qualys discovered that needrestart incorrectly used the RUBYLIB
environment variable to spawn a new Ruby interpreter. A local attacker
could possibly use this issue to execute arbitrary code as root.

USN-7115-1: Waitress vulnerabilities

Read Time:25 Second

It was discovered that Waitress could process follow up requests when
receiving a specially crafted message. An attacker could use this issue to
have the server process inconsistent client requests. This issue only
affected Ubuntu 24.04 LTS and Ubuntu 24.10.(CVE-2024-49768)

Dylan Jay discovered that Waitress could be lead to write to an unexisting
socket after closing the remote connection. An attacker could use this
issue to increase resource utilization leading to a denial of service.

Update description:

Security fix for CVE-2024-52304

Update License field to SPDX.

Build and install the C extensions. Based on the history of security fixes in
later releases, this may close some vulnerabilities and possibly open others,
as both the C and Python HTTP parsing implementations have had their own
distinct issues.

While this backports the fix for CVE-2024-52304, and the fix for CVE-2024-23334
was backported in a previous update, it is very likely that other unmitigated
issues exist in this old release. Unfortunately, updating to a later version in
EPEL8 is impractical at best.

USN-7015-5: Python vulnerabilities

Read Time:1 Minute, 8 Second

USN-7015-1 fixed several vulnerabilities in Python. This update provides
the corresponding update for CVE-2024-6232 and CVE-2024-6923 for python2.7
in Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS
and Ubuntu 22.04 LTS.

Original advisory details:

It was discovered that the Python email module incorrectly parsed email
addresses that contain special characters. A remote attacker could
possibly use this issue to bypass certain protection mechanisms.
(CVE-2023-27043)

It was discovered that Python allowed excessive backtracking while parsing
certain tarfile headers. A remote attacker could possibly use this issue
to cause Python to consume resources, leading to a denial of service.
(CVE-2024-6232)

It was discovered that the Python email module incorrectly quoted newlines
for email headers. A remote attacker could possibly use this issue to
perform header injection. (CVE-2024-6923)

It was discovered that the Python http.cookies module incorrectly handled
parsing cookies that contained backslashes for quoted characters. A remote
attacker could possibly use this issue to cause Python to consume
resources, leading to a denial of service. (CVE-2024-7592)

It was discovered that the Python zipfile module incorrectly handled
certain malformed zip files. A remote attacker could possibly use this
issue to cause Python to stop responding, resulting in a denial of
service. (CVE-2024-8088)
