high Nessus Plugin ID 152715

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLES15 / SLES_SAP15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2021:2791-1 advisory.

- report_vbuild in report.c in Fetchmail before 6.4.20 sometimes omits initialization of the vsnprintf va_list argument, which might allow mail servers to cause a denial of service or possibly have unspecified other impact via long error messages. NOTE: it is unclear whether use of Fetchmail on any realistic platform results in an impact beyond an inconvenience to the client user. (CVE-2021-36386)

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

Solution

Update the affected fetchmail and / or fetchmailconf packages.
