Detail

Antonio Morales discovered an user-after-free flaw in the memory pool allocator in ProFTPD, a powerful modular FTP/SFTP/FTPS server. Interrupting current data transfers can corrupt the ProFTPD memory pool, leading to denial of service, or potentially the execution of arbitrary code.

For the oldstable distribution (stretch), this problem has been fixed in version 1.3.5b-4+deb9u4.

For the stable distribution (buster), this problem has been fixed in version 1.3.6-4+deb10u4.

We recommend that you upgrade your proftpd-dfsg packages.
