The mget function in libmagic/softmagic.c in the Fileinfo component in PHP 5.4.x before 5.4.16 allows remote attackers to cause a denial of service (invalid pointer dereference and application crash) via an MP3 file that triggers incorrect MIME type detection during access to an finfo object.

Security readout for executives and security teams

This is an old PHP Fileinfo denial-of-service issue. A specially crafted MP3 file can crash an application when PHP tries to detect its MIME type through a finfo object. The main business risk is service disruption in legacy PHP 5.4 deployments that inspect user-supplied media files. Exposure is most likely in legacy PHP 5.4.x applications before 5.4.16 that run Fileinfo MIME detection on untrusted MP3s or uploads. Treat this as a legacy exposure cleanup item unless a critical service still runs affected PHP and accepts user files. Patch those systems promptly to reduce crash-driven outages. Mitigation focus: Upgrade affected PHP 5.4.x runtimes to 5.4.16 or later supported vendor guidance.; Prioritize systems processing user-uploaded MP3 or media files through Fileinfo.; Limit untrusted file processing paths until affected runtimes are upgraded..
