CVE-2019-9824

tcp_emu in slirp/tcp_subr.c (aka slirp/src/tcp_subr.c) in QEMU 3.0.0 uses uninitialized data in an snprintf call, leading to Information disclosure.

Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:Rocky Linux module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.

Security Fix(es):

• ntfs-3g: heap-based buffer overflow leads to local root privilege escalation (CVE-2019-9755)

• QEMU: slirp: information leakage in tcp_emu() due to uninitialized stack variables (CVE-2019-9824)

• QEMU: qxl: null pointer dereference while releasing spice resources (CVE-2019-12155)
