Releases

• Ubuntu 24.04 LTS
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

Packages

• python3.12 - An interactive high-level object-oriented language
• python3.8 - An interactive high-level object-oriented language

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)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 24.04

• python3.12 - 3.12.3-1ubuntu0.2
• python3.12-minimal - 3.12.3-1ubuntu0.2

Ubuntu 22.04

• python3.10 - 3.10.12-1~22.04.6
• python3.10-minimal - 3.10.12-1~22.04.6
