Description

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)

 - 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected exim, eximon and / or eximstats-html packages.
