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.

Integer overflow in the _zip_readcdir function in zip_open.c in libzip 0.10 allows remote attackers to execute arbitrary code via the size and offset values for the central directory in a zip archive, which triggers "improper restrictions of operations within the bounds of a memory buffer" and an information leak.

Heap-based buffer overflow in the _zip_readcdir function in zip_open.c in libzip 0.10 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a zip archive with the number of directories set to 0, related to an "incorrect loop construct."
