Debian Security Advisory DSA-4635-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
February 26, 2020 https://www.debian.org/security/faq
Package : proftpd-dfsg
CVE ID : CVE-2020-9273
Debian Bug : 951800
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.
For the detailed security status of proftpd-dfsg please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/proftpd-dfsg
