The vulnerability allows a remote attacker to perform a DoS attack on a target system. The vulnerability exists due to a memory leak in the read_header () function in list.c. A remote attacker could pass a specially crafted archive to the application and cause a memory leak, ultimately leading to a denial of service.Identifier of the Information Security Threat Data Bank of the FSTEC of Russia: BDU:2021-02357
