CVE-2013-7345

The BEGIN regular expression in the awk script detector in magic/Magdir/commands in file before 5.15 uses multiple wildcards with unlimited repetitions, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted ASCII file that triggers a large amount of backtracking, as demonstrated via a file with many newline characters (CVE-2013-7345).

Updated php packages fix security vulnerability:

The BEGIN regular expression in the awk script detector in magic/Magdir/commands in file before 5.15 uses multiple wildcards with unlimited repetitions, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted ASCII file that triggers a large amount of backtracking, as demonstrated via a file with many newline characters (CVE-2013-7345).

PHP contains a bundled copy of the file utility's libmagic library, so it was vulnerable to this issue. It has been updated to versions 5.4.27 and 5.5.11, which fix this issue and several other bugs.

Also, the timezonedb PHP PECL module has been updated to its newest version.

Additionally, php-apc has been rebuilt against the updated php packages.

These are all security issues fixed in the apache2-mod_php7-7.0.14-1.4 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the apache2-mod_php5-5.6.28-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the php8-8.0.11-1.1 package on the GA media of openSUSE Tumbleweed.

Mike Frysinger discovered that the file awk script detector used multiple wildcard with unlimited repetitions. An attacker could use this issue to cause file to consume resources, resulting in a denial of service. (CVE-2013-7345)

Francisco Alonso discovered that file incorrectly handled certain CDF documents. A attacker could use this issue to cause file to hang or crash, resulting in a denial of service. (CVE-2014-0207, CVE-2014-3478, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487)

Jan Kaluža discovered that file did not properly restrict the amount of data read during regex searches. An attacker could use this issue to cause file to consume resources, resulting in a denial of service. (CVE-2014-3538)
