Vulnerability from variot

An attacker who submits a crafted tar file with size in header struct being 0 may be able to trigger an calling of malloc(0) for a variable gnu_longname, causing an out-of-bounds read. feep.net of libtar Products from other vendors have out-of-bounds read vulnerabilities.Information is obtained and service operation is interrupted (DoS) It may be in a state. openEuler is an operating system of the Open Atom Open Source Foundation. There are security vulnerabilities in openEuler 20.03-LTS-SP1, 20.03-LTS-SP3 and 22.03-LTS versions of the Open Atom Open Source Foundation. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256
