Alpine: drupal7: security update to 7.62-r0
high Tenable Self-Hosted Container Security Plugin ID 426125
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- PEAR Archive_Tar version 1.4.3 and earlier contains a CWE-502, CWE-915 vulnerability in the Archive_Tar
class. There are several file operations with `$v_header['filename']` as parameter (such as file_exists,
is_file, is_dir, etc). When extract is called without a specific prefix path, we can trigger
unserialization by crafting a tar file with `phar://[path_to_malicious_phar_file]` as path. Object
injection can be used to trigger destruct in the loaded PHP classes, e.g. the Archive_Tar class itself.
With Archive_Tar object injection, arbitrary file deletion can occur because
`@unlink($this->_temp_tarname)` is called. If another class with useful gadget is loaded, it may possible
to cause remote code execution that can result in files being deleted or possibly modified. This
vulnerability appears to have been fixed in 1.4.4. (CVE-2018-1000888)
