The foreach function in ext/ccsv.c in Ccsv 1.1.0 allows remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact via a crafted file. NOTE: This has been disputed and it is argued that this is not present in version 1.1.0.
Weakness
The product calls free() twice on the same memory address.
