CVE-2020-6162Network attack vector

Daemon startup crash via uninitialized value

Published Jan 10, 2020 · Updated Aug 4, 2024

Out-of-bounds read in Bftpd 5.3 allows attackers to crash the FTP daemon process during startup via unspecified vectors. The hidegroups_init function in dirlist.c uses an uninitialized value for an out-of-bounds memory read. Public sources do not identify the input or configuration that triggers the startup path, and the documented consequence is a daemon crash.
