Description

This security bulletin contains information about 9 secuirty vulnerabilities.

1) Incorrect Regular Expression (CVE-ID: CVE-2024-6232)

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

The vulnerability exists due to insufficient validation of .tar archives when processing it with regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

2) Command Injection (CVE-ID: CVE-2024-6923)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to insufficient validation of newlines for email headers when serializing an email message. A remote attacker can inject arbitrary headers into serialized email messages.

3) Resource exhaustion (CVE-ID: CVE-2024-7592)

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

The vulnerability exists due to application does not properly control consumption of internal resources within the 'http.cookies' standard library module when parsing cookies that contained backslashes for quoted characters in the cookie value. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

4) Infinite loop (CVE-ID: CVE-2024-8088)

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

The vulnerability exists due to infinite loop within the the CPython "zipfile" module affecting "zipfile.Path". A remote attacker can consume all available system resources and cause denial of service conditions.

5) Path traversal (CVE-ID: CVE-2024-12718)

The vulnerability allows a remote attacker to modify arbitrary files on the system.

The vulnerability exists due to input validation error in the tarfile module. A remote attacker can pass a specially crafted archive to the application and modify some file metadata (e.g. last modified) with filter="data" or file permissions (chmod) with filter="tar" of files outside the extraction directory.

6) Link following (CVE-ID: CVE-2025-4138)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to an insecure link following issue when extracting data from an archive in the tarfile module. A remote attacker can pass a specially crafted archive to the application and overwrite arbitrary files outside the destination directory during extraction with filter="data"..

7) Link following (CVE-ID: CVE-2025-4330)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to an insecure link following issue when extracting data from an archive in the tarfile module. A remote attacker can pass a specially crafted archive to the application and overwrite arbitrary files outside the destination directory.

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

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.

9) Path traversal (CVE-ID: CVE-2025-4517)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to input validation error in the tarfile module when extracting files from an archive with filter="data". A remote attacker can pass specially crafted archive to the application and write files to arbitrary locations on the system outside the extraction directory.
