Vulnerability details

The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to use of uninitialized resource in zipfileInflate() in the zipfile extension when processing a crafted ZIP file through the zipfile() functionality. A remote attacker can supply a crafted ZIP file with a forged uncompressed size to disclose sensitive information.

Only instances where the zipfile extension is enabled and used to process untrusted ZIP content are vulnerable.
