Summary:

An update for libpcap is now available for EulerOS Virtualization release 2.11.0

EulerOS Security has rated this update as having a security impact of Low.A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.General:

Libpcap provides a portable framework for low-level network monitoring. Libpcap can provide network statistics collection, security monitoring and network debugging. Since almost every system vendor provides a different interface for packet capture, the libpcap authors created this system-independent API to ease in porting and to alleviate the need for several system-dependent packet capture modules in each application. Install libpcap if you need to do low-level network traffic monitoring on your network.

Security Fix(es):

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)Legal Disclaimer:
