hw/9pfs/cofile.c and hw/9pfs/9p.c in QEMU can modify an fid path while it is being accessed by a second thread, leading to (for example) a use-after-free outcome. hw/9pfs/cofile.c y hw/9pfs/9p.c en QEMU pueden modificar una ruta fid mientras un segundo hilo accede a ella, lo que conduce a, por ejemplo, un uso de memoria previamente liberada. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00042.html http://www.openwall.com/lists/oss-security/2018/11/20/1 https://lists.debian.org/debian-lts-announce/2019/01/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CGCFIFSIWUREEQQOZDZFBYKWZHXCWBZN https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg01139.html https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg02795.html https://seclists.org/bugtraq/2019/M • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2018-17958
Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used. Qemu tiene un desbordamiento de búfer en rtl8139_do_receive en hw/net/rtl8139.c debido a que se emplea un tipo de datos de enteros incorrecto. An integer overflow issue was found in the RTL8139 NIC emulation in QEMU. It could occur while receiving packets over the network if the size value is greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. • http://www.openwall.com/lists/oss-security/2018/10/08/1 http://www.securityfocus.com/bid/105556 https://access.redhat.com/errata/RHSA-2019:2425 https://access.redhat.com/errata/RHSA-2019:2553 https://lists.debian.org/debian-lts-announce/2019/01/msg00023.html https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg03269.html https://seclists.org/bugtraq/2019/May/76 https://usn.ubuntu.com/3826-1 https://www.debian.org/security/2019/dsa-4454 https://access& • CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
