Description

This security bulletin contains information about 5 vulnerabilities.


1) Expected behavior violation (CVE-ID: CVE-2025-4435)

CWE-ID: CWE-440 - Expected Behavior Violation

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


The vulnerability allows a remote attacker to change expected behavior. 

The vulnerability exists due to an error when using a TarFile.errorlevel = 0 and extracting with a filter the documented behavior. A remote attacker can force the application to extract files that were meant to be skipped. 


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

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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


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.


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

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

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


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.


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

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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


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.


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

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

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


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"..
