-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2019-24edff97c6 2019-07-03 00:43:02.372094 --------------------------------------------------------------------------------
Name : php-brumann-polyfill-unserialize Product : Fedora EPEL 7 Version : 1.0.3 Release : 1.el7 URL : https://github.com/dbrumann/polyfill-unserialize Summary : Backports unserialize options introduced in PHP 7.0 Description : Backports unserialize options introduced in PHP 7.0 to older PHP versions. This was originally designed as a Proof of Concept for Symfony Issue [#21090](https://github.com/symfony/symfony/pull/21090).
You can use this package in projects that rely on PHP versions older than PHP 7.0. In case you are using PHP 7.0+ the original unserialize() will be used instead.
From the [documentation](https://secure.php.net/manual/en/function.unserialize.php):
Warning: Do not pass untrusted user input to unserialize(). Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this.
This warning holds true even when `allowed_classes` is used.
Autoloader: /usr/share/php/Brumann/Polyfill/autoload.php
-------------------------------------------------------------------------------- Update Information:
## php-typo3-phar-stream-wrapper2 ### v2.1.2 Handling mime-type & Windows paths #### Resolved Issues - #34: Normalize resolved Windows path to Unix-style - #42: Avoid analysing non-phar files on alias resolving - #40: Add Windows tests using AppVeyor - #33: Add alternative mime-type resolving (without ext- fileinfo) ### v2.1.1 Phar Alias Handling & Performance Releases v3.1.1 and v.2.1.1 aim to overcome drawbacks in Phar's alias resolving from Phar stub as well as solving performance aspects. ### v2.1.0 Phar Alias Handling #### Description Releases v3.1.0 and v.2.1.0 aim to overcome drawbacks in Phar's alias resolving (either by Phar archives using `Phar::setAlias()` in meta-data or `Phar::mapPhar()` in stub code). Merged pull-requests - Phar alias resolving (v3: #10, #12, v2: #14, #15) - Phar alias handling and (v3: #16, #17, v2: #20) #### Migration In case custom Assertable interceptors have been used, path resolving has to be adjusted in order to make use of alias resolving features. ##### before - example in v3.0.1 $baseFile = Helper::determineBaseFile($path); ##### after - example in v3.1.0 $invocation = Manager::instance()->resolve($path); $baseName = $invocation->getBaseName(); // previously called $baseFile #### Open Issues There have been reports about flaws using `stream_select()` and according `stream_cast()` in `PharStreamWrapper`. Since it was not possible to reproduce the behavior in an isolated scenario and specific platform requiresments were not clear, these aspects have not been covered by these releses - see #8 and #19 for details. #### Features - added low-level `Phar\Reader` for stub & meta- data (incl. alias) and their model representations - added `Resolver\PharInvocationResolver` in order to resolve/handle alias names - added `Interceptor\ConjunctionInterceptor` for combining multiple interceptors - added `Interceptor\PharMetaDataInterceptor` for actually testing against insecure deserialization in meta-data of Phar archives ## php-brumann-polyfill- unserialize Backports unserialize options introduced in PHP 7.0 to older PHP versions.
