CVSS v3.1
8.1
Alta
| Vetor | AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
PHP versions 7.1.x through 7.1.26
PHP versions 7.3.x through 7.3.2
Description
The issue is related to a buffer overflow in the
phar tar writeheaders int function in ext/phar/tar.c of the PHP interpreter. This can be exploited by a remote attacker to execute arbitrary code. The buffer overflow occurs via a long link value. However, the vendor notes that the link value is used only when an archive contains a symlink, which currently cannot happen, making a practical attack usually impossible.Recommendations
For PHP versions 7.1.x through 7.1.26, update to version 7.1.27 or later.
For PHP versions 7.3.x through 7.3.2, update to version 7.3.3 or later.
