Fedora Update Notification
FEDORA-2019-af7bef7165
2019-06-28 05:20:24.267217
——————————————————————————–

Name : php-brumann-polyfill-unserialize
Product : Fedora 29
Version : 1.0.3
Release : 1.fc29
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-
