Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: flow_dissector: do not dissect PPPoE
 PFC frames RFC 2516 Section 7 states that Protocol Field Compression (PFC) is NOT RECOMMENDED for PPPoE.
 In practice, pppd does not support negotiating PFC for PPPoE sessions, and the flow dissector driver has
 assumed an uncompressed frame until the blamed commit. During the review process of that commit [1],
 support for PFC is suggested. However, having a compressed (1-byte) protocol field means the subsequent
 PPP payload is shifted by one byte, causing 4-byte misalignment for the network header and an unaligned
 access exception on some architectures. The exception can be reproduced by sending a PPPoE PFC frame to an
 ethernet interface of a MIPS board, with RPS enabled, even if no PPPoE session is active on that
