| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2026-9538 | Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header. _read_tar() reads each entry's payload with $handle->read($$data, $block), where $block is derived from the entry's 12-byte size field in the tar header with no upper bound on that value. A crafted header declaring a multi-gigabyte size causes Perl to allocate a scalar of that size. | 9b29abf9-4ab0-4765-b253-1875cd9b441e | 7.5 | 0.44% | 2026-05-25 | 2026-06-17 |
| CVE-2026-42497 | Archive::Tar versions before 3.08 for Perl extract hardlinks to attacker controlled paths outside the extraction directory. _make_special_file() passes the tar header's linkname to link() without validating it against absolute paths or .. segments, creating a hardlink that shares the victim file's inode. A subsequent write through the extracted name modifies the victim file, and the post-extraction chmod, chown, and utime block in _extract_file() (guarded only against symlinks via -l) applies | 9b29abf9-4ab0-4765-b253-1875cd9b441e | 7.5 | 0.40% | 2026-05-25 | 2026-06-17 |
| CVE-2026-42496 | Archive::Tar versions before 3.08 for Perl extract symlinks with attacker controlled targets outside the extraction directory. _make_special_file() passes the tar header's linkname to symlink() without validating it against absolute paths or .. segments. The secure-extract mode check that guards regular file extraction does not cover the symlink target. A subsequent open through the extracted name reads or writes the attacker chosen path. | 9b29abf9-4ab0-4765-b253-1875cd9b441e | 9.1 | 0.47% | 2026-05-25 | 2026-06-17 |
| CVE-2018-12015 | In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink and a regular file with the same name. | [email protected] | 7.5 | 8.21% | 2018-06-07 | 2026-06-16 |
| CVE-2007-4829 | Directory traversal vulnerability in the Archive::Tar Perl module 1.36 and earlier allows user-assisted remote attackers to overwrite arbitrary files via a TAR archive that contains a file whose name is an absolute path or has ".." sequences. | [email protected] | 6.8 | 4.32% | 2007-11-02 | 2026-06-16 |
