AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions zziplib versions 0.13.56 through 0.13.62

Description The issue is related to a heap-based buffer overflow in the zzip get64 function, located in the fetch.c file of zziplib. This can be exploited by remote attackers using a crafted ZIP file, leading to a denial of service (crash).

Recommendations For zziplib versions 0.13.56 through 0.13.62, consider avoiding the use of the zzip get64 function until a patch is available. As a temporary workaround, restrict the handling of ZIP files from untrusted sources to minimize the risk of exploitation.
