VUL-1: CVE-2021-3593: qemu: slirp,libslirp: invalid pointer initialization may lead to information disclosure (udp6)
Last modified: 2024-07-26 09:52:31 UTC
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The function udp6_input() handles requests for the udp protocol from the guest. While processing a udp packet that is smaller than the size of the udphdr structure it uses memory from outside the working mbuf buffer. This issue may lead to out of bound read access or indirect memory disclosure to the guest.
