 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4384-1 [email protected] https://www.debian.org/lts/security/ Paride Legovini November 26, 2025 https://wiki.debian.org/LTS

 Package : samba Version : 2:4.13.13+dfsg-1~deb11u7 CVE ID : CVE-2025-9640

 A flaw was found in Samba, in the vfs_streams_xattr module, where uninitialized heap memory could be written into alternate data streams. This allows an authenticated user to read residual memory content that may include sensitive data, resulting in an information disclosure vulnerability.

 For Debian 11 bullseye, this problem has been fixed in version 2:4.13.13+dfsg-1~deb11u7.

 We recommend that you upgrade your samba packages.

 For the detailed security status of samba please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/samba
