Description

This security bulletin contains information about 3 vulnerabilities.

1) Input validation error (CVE-ID: CVE-2025-1795)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to insufficient validation of user-supplied input in Lib/email/_header_value_parser.py. A remote attacker can pass specially crafted input to the application and manipulate headers in an email message.

2) Use-after-free (CVE-ID: CVE-2025-4516)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error when using the bytes.decode("unicode_escape", error="ignore|replace") function call. A remote attacker can pass a specially crafted input to the application and perform a denial of service (DoS) attack.

3) Infinite loop (CVE-ID: CVE-2025-8194)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in the “tarfile” module when handling tar archives with negative offsets. A remote attacker can pass a specially crafted tar archive to the application and consume all available system resources, resulting in a deadlock and a denial of service.
