| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2026-5704 | A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection. | [email protected] | 5.0 | 0.43% | 2026-04-06 | 2026-04-22 |
| CVE-2025-45582 | GNU Tar through 1.35 allows file overwrite via directory traversal in crafted TAR archives, with a certain two-step process. First, the victim must extract an archive that contains a ../ symlink to a critical directory. Second, the victim must extract an archive that contains a critical file, specified via a relative pathname that begins with the symlink name and ends with that critical file's name. Here, the extraction follows the symlink and overwrites the critical file. This bypasses the prot | [email protected] | 4.1 | 0.43% | 2025-07-11 | 2025-11-02 |
| CVE-2023-39804 | In GNU tar before 1.35, mishandled extension attributes in a PAX archive can lead to an application crash in xheader.c. | [email protected] | 6.2 | 0.28% | 2024-03-27 | 2025-11-04 |
| CVE-2022-48303 | GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has not been demonstrated. The issue occurs in from_header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters. | [email protected] | 5.5 | 4.52% | 2023-01-30 | 2025-03-27 |
| CVE-2021-20193 | A flaw was found in the src/list.c of tar 1.33 and earlier. This flaw allows an attacker who can submit a crafted input file to tar to cause uncontrolled consumption of memory. The highest threat from this vulnerability is to system availability. | [email protected] | 3.3 | 1.09% | 2021-03-26 | 2025-05-05 |
| CVE-2019-9923 | pax_decode_header in sparse.c in GNU Tar before 1.32 had a NULL pointer dereference when parsing certain archives that have malformed extended headers. | [email protected] | 7.5 | 3.03% | 2019-03-22 | 2025-08-06 |
| CVE-2018-20482 | GNU Tar through 1.30, when --sparse is used, mishandles file shrinkage during read access, which allows local users to cause a denial of service (infinite read loop in sparse_dump_region in sparse.c) by modifying a file that is supposed to be archived by a different user's process (e.g., a system backup running as root). | [email protected] | 4.7 | 0.53% | 2018-12-26 | 2024-11-21 |
| CVE-2016-6321 | Directory traversal vulnerability in the safer_name_suffix function in GNU tar 1.14 through 1.29 might allow remote attackers to bypass an intended protection mechanism and write to arbitrary files via vectors related to improper sanitization of the file_name parameter, aka POINTYFEATHER. | [email protected] | 7.5 | 15.15% | 2016-12-09 | 2026-05-06 |
| CVE-2010-0624 | Heap-based buffer overflow in the rmt_read__ function in lib/rtapelib.c in the rmt client functionality in GNU tar before 1.23 and GNU cpio before 2.11 allows remote rmt servers to cause a denial of service (memory corruption) or possibly execute arbitrary code by sending more data than was requested, related to archive filenames that contain a : (colon) character. | [email protected] | 6.8 | 4.75% | 2010-03-15 | 2026-04-29 |
| CVE-2007-4476 | Buffer overflow in the safer_name_suffix function in GNU tar has unspecified attack vectors and impact, resulting in a "crashing stack." | [email protected] | 7.5 | 14.90% | 2007-09-05 | 2026-04-23 |
| CVE-2007-4131 | Directory traversal vulnerability in the contains_dot_dot function in src/names.c in GNU tar allows user-assisted remote attackers to overwrite arbitrary files via certain //.. (slash slash dot dot) sequences in directory symlinks in a TAR archive. | [email protected] | 6.8 | 2.74% | 2007-08-25 | 2026-04-23 |
| CVE-2006-6097 | GNU tar 1.16 and 1.15.1, and possibly other versions, allows user-assisted attackers to overwrite arbitrary files via a tar file that contains a GNUTYPE_NAMES record with a symbolic link, which is not properly handled by the extract_archive function in extract.c and extract_mangle function in mangle.c, a variant of CVE-2002-1216. | [email protected] | 4.0 | 10.75% | 2006-11-24 | 2026-04-23 |
| CVE-2006-0300 | Buffer overflow in tar 1.14 through 1.15.90 allows user-assisted attackers to cause a denial of service (application crash) and possibly execute code via unspecified vectors involving PAX extended headers. | [email protected] | 5.1 | 5.05% | 2006-02-24 | 2026-04-16 |
| CVE-2005-1918 | The original patch for a GNU tar directory traversal vulnerability (CVE-2002-0399) in Red Hat Enterprise Linux 3 and 2.1 uses an "incorrect optimization" that allows user-assisted attackers to overwrite arbitrary files via a crafted tar file, probably involving "/../" sequences with a leading "/". | [email protected] | 2.6 | 2.86% | 2005-12-31 | 2026-04-16 |
| CVE-2005-2541 | Tar 1.15.1 does not properly warn the user when extracting setuid or setgid files, which may allow local users or remote attackers to gain privileges. | [email protected] | 10.0 | 3.99% | 2005-08-10 | 2026-04-16 |
| CVE-2002-1216 | GNU tar 1.13.19 and other versions before 1.13.25 allows remote attackers to overwrite arbitrary files via a symlink attack, as the result of a modification that effectively disabled the security check. | [email protected] | 5.0 | 1.57% | 2002-10-28 | 2026-06-16 |
| CVE-2002-0399 | Directory traversal vulnerability in GNU tar 1.13.19 through 1.13.25, and possibly later versions, allows attackers to overwrite arbitrary files during archive extraction via a (1) "/.." or (2) "./.." string, which removes the leading slash but leaves the "..", a variant of CVE-2001-1267. | [email protected] | 5.0 | 3.59% | 2002-10-10 | 2026-06-16 |
