CVE-2012-1163

Publication date 12 July 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
