Google: net-libs/libpcap: security update to 18244.151.57

medium Tenable Self-Hosted Container Security Plugin ID 451414

Description

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

- In affected libpcap versions during the setup of a remote packet capture the internal function
sock_initaddress() calls getaddrinfo() and possibly freeaddrinfo(), but does not clearly indicate to the
caller function whether freeaddrinfo() still remains to be called after the function returns. This makes
it possible in some scenarios that both the function and its caller call freeaddrinfo() for the same
allocated memory block. A similar problem was reported in Apple libpcap, to which Apple assigned
CVE-2023-40400. (CVE-2023-7256)

Solution

Update the net-libs/libpcap library and its related packages to version 18244.151.57 or later.
