How to fix?

Upgrade SLES:16.0.0 libpcap1 to version 1.10.5-160000.4.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libpcap1 package and not the libpcap1 package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

pcap_ether_aton() is an auxiliary function in libpcap, it takes a string argument and returns a fixed-size allocated buffer. The string argument must be a well-formed MAC-48 address in one of the supported formats, but this requirement has been poorly documented. If an application calls the function with an argument that deviates from the expected format, the function can read data beyond the end of the provided string and write data beyond the end of the allocated buffer.
