 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3829-1 [email protected] https://www.debian.org/lts/security/ Bastien Roucaris June 15, 2024 https://wiki.debian.org/LTS

 Package : sendmail Version : 8.15.2-14~deb10u2 CVE ID : CVE-2023-51765 Debian Bug : 1059386

 sendmail allowed SMTP smuggling in certain configurations.
 Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because sendmail supports <LF>.<CR><LF> but some other popular e-mail servers do not.

 This particular injection vulnerability has been closed, unfortunatly full closure need to reject mail that contain NUL (0x00 byte).

 This is slighly non conformant with RFC and could be opt-out by setting confREJECT_NUL to 'false' in sendmail.mc file.

 For Debian 10 buster, this problem has been fixed in version 8.15.2-14~deb10u2.

 We recommend that you upgrade your sendmail packages.

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

Solution

Upgrade the libmilter-dev packages.
