"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are
affected by a vulnerability as referenced in the SUSE-SU-2023:4965-1 advisory.
- A vulnerability classified as problematic has been found in ppp. Affected is the function dumpppp of the
file pppdump/pppdump.c of the component pppdump. The manipulation of the argument spkt.buf/rpkt.buf leads
to improper validation of array index. The real existence of this vulnerability is still doubted at the
moment. The name of the patch is a75fb7b198eed50d769c80c36629f38346882cbf. It is recommended to apply a
patch to fix this issue. VDB-216198 is the identifier assigned to this vulnerability. NOTE: pppdump is not
used in normal process of setting up a PPP connection, is not installed setuid-root, and is not invoked
automatically in any scenario. (CVE-2022-4603)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
