Title:	Huawei EulerOS: Security Advisory for php-pear (EulerOS-SA-2019-1147)
Summary:	The remote host is missing an update for the Huawei EulerOS 'php-pear' package(s) announced via the EulerOS-SA-2019-1147 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'php-pear' package(s) announced via the EulerOS-SA-2019-1147 advisory. Vulnerability Insight: 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. (CVE-2018-1000888) Affected Software/OS: 'php-pear' package(s) on Huawei EulerOS V2.0SP5. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
