8) 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.
9) Race condition (CVE-ID: CVE-2024-12747)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to a race condition when handling symbolic links. A local user can replace a file with a symbolic link, bypass implemented protection in rsync that prevents software from following symbolic links and read contents of arbitrary files on the system with elevated privileges.
10) Security features bypass (CVE-ID: CVE-2024-35195)
The vulnerability allows a local user to compromise the target system.
The vulnerability exists due to the session object does not verify requests after making first request with verify=False. A local administrator can bypass authentication.
11) Off-by-one (CVE-ID: CVE-2024-52533)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to an off-by-one error in gio/gsocks4aproxy.c when handling responses from SOCKS4 proxy. A remote attacker can trick the victim into connecting to a malicious SOCKS4 proxy server, trigger an off-by-one error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
12) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2025-3576)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to usage of RC4-HMAC-MD algorithm for GSSAPI-protected messages. A remote attacker can perform MitM attack.
13) 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"..
14) 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.
15) Integer overflow (CVE-ID: CVE-2025-4373)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the g_string_insert_unichar() function in glib/gstring.c. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
16) Expected behavior violation (CVE-ID: CVE-2025-4435)
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.
17) 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.
18) Resource management error (CVE-ID: CVE-2025-5702)
The vulnerability allows a remote attacker to alter application's behavior.
The vulnerability exists due to an error in strcmp implementation optimized for the Power10 processor. The function writes to vector registers v20 to v31 without saving contents from the caller (those registers are defined as non-volatile registers by the powerpc64le ABI), resulting in overwriting of its contents and potentially altering control flow of the caller, or leaking the input strings to the function to other parts of the program.
19) Improper access control (CVE-ID: CVE-2025-6020)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper access restrictions within the pam_namespace module when handling user-controlled paths. A local user can use specially crafted symlinks and race conditions to execute arbitrary code as root.
20) Buffer overflow (CVE-ID: CVE-2025-6965)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing aggregated terms. A remote attacker can pass specially crafted input to the application where the number of aggregate terms exceeds the number of columns available, trigger memory corruption and perform a denial of service (DoS) attack.
21) Use-after-free (CVE-ID: CVE-2025-7425)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the xsltSetSourceNodeFlags() function. A remote attacker can pass specially crafted XML input to the application, trigger memory corruption and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
22) Buffer overflow (CVE-ID: CVE-2025-25724)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing .tar files within the list_item_verbose() function in tar/util.c. A remote attacker can create a specially crafted archive, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
23) Race condition (CVE-ID: CVE-2025-40909)
The vulnerability allows a local user to tamper with application's behavior.
The vulnerability exists due to a race condition if a directory handle is open at thread creation. A local user can exploit the race and force the application to load code or access files from unexpected location.
24) Path traversal (CVE-ID: CVE-2025-47273)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to input validation error when processing directory traversal sequences in package_index.py. A remote attacker can trick the victim into installing a specially crafted script and overwrite arbitrary files on the system, leading to code execution.
