Package : freerdp2 Version : 2.3.0+dfsg1-2+deb11u3 CVE ID : CVE-2022-24882 CVE-2022-39320 Debian Bug : 1024511 1098355

Multiple vulnerabilties have been found in freelrdp2, a free implementation of the Remote Desktop Protocol (RDP) which potentially allows potential buffer overreads or not properly abort NTLM authentication on empty password, if used as server.

Additonally this update fixes a regression with DLA-4053-1 affecting drive sharing.

CVE-2022-24882

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP). In versions prior to 2.7.0, NT LAN Manager (NTLM) authentication does not properly abort when someone provides and empty password value. This issue affects FreeRDP based RDP Server implementations. RDP clients are not affected.

CVE-2022-39320

FreeRDP is a free remote desktop protocol library and clients.
Affected versions of FreeRDP may attempt integer addition on too narrow types leads to allocation of a buffer too small holding the data written. A malicious server can trick a FreeRDP based client to read out of bound data and send it back to the server. This issue has been addressed in version 2.9.0 and all users are advised to upgrade. Users unable to upgrade should not use the `/usb` redirection switch.

For Debian 11 bullseye, these problems have been fixed in version 2.3.0+dfsg1-2+deb11u3.

We recommend that you upgrade your freerdp2 packages.
