Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2018-10756
CWEhttps://cwe.mitre.org/data/definitions/416.html

Use-after-free in libtransmission/variant.c in Transmission before 3.00 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted torrent file.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
