Description Laura Pardo 2018-07-04 21:12:26 UTC 
A flaw was found in ZZIPlib 0.13.67, there is a bus error caused by loading of a misaligned address (when handling disk64_trailer local entries) in __zzip_fetch_disk_trailer (zzip/zip.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
