An update for libpcap is now available for openEuler-24.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-1111 Final 1.0 1.0 2026-01-16 Initial 2026-01-16 2026-01-16 openEuler SA Tool V1.0 2026-01-16 libpcap security update An update for libpcap is now available for openEuler-24.03-LTS-SP2 This is the official web site of tcpdump, a powerful command-line packet analyzer; and libpcap, a portable C/C++ library for network traffic capture. 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) An update for libpcap is now available for openEuler-24.03-LTS-SP2. openEuler Security has rated this update as having a security impact of low.
