A flaw was found in ZZIPlib 0.13.67, there is a bus error caused by loading of a misaligned address (when handling disk64trailer local entries) in zzipfetchdisktrailer (zzip/zip.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

In ZZIPlib 0.13.67, there is a bus error caused by loading of a misaligned address in the zzipdiskfindfirst function of zzip/mmapped.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

In ZZIPlib 0.13.67, there is a bus error (when handling a disk64trailer seek value) caused by loading of a misaligned address in the zzipdiskfindfirst function of zzip/mmapped.c.

In ZZIPlib 0.13.67, there is a memory alignment error and bus error in the zzipfetchdisktrailer function of zzip/zip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted zip file.

In ZZIPlib 0.13.67, 0.13.66, 0.13.65, 0.13.64, 0.13.63, 0.13.62, 0.13.61, 0.13.60, 0.13.59, 0.13.58, 0.13.57 and 0.13.56 there is a segmentation fault caused by invalid memory access in the zzipdiskfread function (zzip/mmapped.c) because the size variable is not validated against the amount of file->stored data.
