CVSS: 3.8EPSS: 0%CPEs: 6EXPL: 0CVE-2021-3593 – QEMU: slirp: invalid pointer initialization may lead to information disclosure (udp6)
https://notcve.org/view.php?id=CVE-2021-3593
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp6_input() function and could occur while processing a udp packet that is smaller than the size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0. • https://bugzilla.redhat.com/show_bug.cgi?id=1970487 https://lists.debian.org/debian-lts-announce/2022/04/msg00002.html https://lists.debian.org/debian-lts-announce/2023/03/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GCKWZWY64EHTOQMLVLTSZ4AA27EWRJMH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SGPQZFVJCFGDSISFXPCQTTBBD7QZLJKI https://security.gentoo.org/glsa/202107-44 https://security.netapp.com/advisory/ntap& • CWE-824: Access of Uninitialized Pointer •
