Heap-based buffer overflow in the zipreadcdir function in zipopen.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."

Integer overflow in the zipreadcdir function in zipopen.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.
