Description

An issue was discovered in PHP 7.x before 7.1.27 and 7.3.x before 7.3.3. phar_tar_writeheaders_int in ext/phar/tar.c has a buffer overflow via a long link value. NOTE: The vendor indicates that the link value is used only when an archive contains a symlink, which currently cannot happen: "This issue allows theoretical compromise of security, but a practical attack is usually impossible.

Affected configurations

• php php (>= 7.0.0 < 7.1.27) • php php (>= 7.3.0 < 7.3.3) • canonical ubuntu linux 12.04 • canonical ubuntu linux 14.04 • opensuse leap 42.3
