    Package        : exim4     Version        : 4.94.2-7+deb11u4     CVE ID         : CVE-2021-38371 CVE-2022-3559 CVE-2023-42117 CVE-2023-42119     Debian Bug     : 992172

    Multiple potential security vulnerabilities have been addressed in exim4, a     mail transport agent. These issues may allow remote attackers to disclose     sensitive information or execute arbitrary code but only if Exim4 is run behind     or with untrusted proxy servers or DNS resolvers. If your proxy-protocol proxy     or DNS resolver are trustworthy, you are not affected.

    For Debian 11 bullseye, these problems have been fixed in version     4.94.2-7+deb11u4.

    We recommend that you upgrade your exim4 packages.

    For the detailed security status of exim4 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/exim4

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2024:0007-1 advisory.

  - A vulnerability was found in Exim and classified as problematic. This issue affects some unknown     processing of the component Regex Handler. The manipulation leads to use after free. The name of the patch     is 4e9ed49f8f12eb331b29bd5b6dc3693c520fddc2. It is recommended to apply a patch to fix this issue. The     identifier VDB-211073 was assigned to this vulnerability. (CVE-2022-3559)

  - NTLM Challenge Out-Of-Bounds Read Information Disclosure Vulnerability [epel-all] (CVE-2023-42114)

  - AUTH Out-Of-Bounds Write Remote Code Execution Vulnerability [epel-all] (CVE-2023-42115)

  - Exim SMTP Challenge Stack-based Buffer Overflow Remote Code Execution Vulnerability (CVE-2023-42116,     CVE-2023-42117)

  - dnsdb Out-Of-Bounds Read Information Disclosure Vulnerability [epel-all] (CVE-2023-42119)

  - Exim before 4.97.1 allows SMTP smuggling in certain PIPELINING/CHUNKING 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 Exim supports <LF>.<CR><LF> but some     other popular e-mail servers do not. (CVE-2023-51766)
