------------------------------------------------------------------------- Debian LTS Advisory DLA-3251-1 [email protected] https://www.debian.org/lts/security/ Markus Koschany December 29, 2022 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : libcommons-net-java Version : 3.6-1+deb10u1 CVE ID : CVE-2021-37533 Debian Bug : 1025910

ZeddYu Lu discovered that the FTP client of Apache Commons Net, a Java client API for basic Internet protocols, trusts the host from PASV response by default. A malicious server can redirect the Commons Net code to use a different host, but the user has to connect to the malicious server in the first place. This may lead to leakage of information about services running on the private network of the client.

For Debian 10 buster, this problem has been fixed in version 3.6-1+deb10u1.

We recommend that you upgrade your libcommons-net-java packages.

For the detailed security status of libcommons-net-java please refer to its security tracker page at:
