PHP ZIP extension (libzip) can crash or be exploited

CVE-2015-2331 · published 11 years ago
Summary

Older versions of PHP's ZIP handling, which rely on libzip 0.11.2 or earlier, can be triggered by a specially crafted ZIP file to cause the application to crash or potentially run unwanted code. This affects PHP releases before 5.4.39, 5.5.23, and 5.6.7, as well as any software using the same libzip library. Upgrade PHP and libzip to the latest available versions to protect your systems.

Integer overflow in the _zip_cdir_new function in zip_dirent.c in libzip 0.11.2 and earlier, as used in the ZIP extension in PHP before 5.4.39, 5.5.x before 5.5.23, and 5.6.x before 5.6.7 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a ZIP archive that contains many entries, leading to a heap-based buffer overflow.
