Synopsis

The remote Debian host is missing a security-related update.

Description

Antonio Morales discovered an use-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.

Upgrade the proftpd-dfsg packages.

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.
