Description Laura Pardo 2018-02-05 18:43:50 EST 
A flaw was found in ZZIPlib 0.13.67, there is a bus error caused by loading of a misaligned address in the zzip_disk_findfirst function of zzip/mmapped.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.
