Echo: libpcap: security update to 1.10.5-2+e1

low Tenable Cloud Security Plugin ID 463003

Description

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

 - 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. (CVE-2025-11961)

Solution

Update the libpcap library and its related packages to version 1.10.5-2+e1 or later.
