CVE-2012-1162
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,…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.02%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
