Exploitability:
CWE CWE-190
CAPEC
  • Forced Integer Overflow
    This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.

    description Integer overflows in the processing of packets in network cards emulated by QEMU, a fast processor emulator, could result in denial of service. In addition this update backports support to passthrough the new CPU features added in the intel-microcode update shipped in DSA 4273 to x86-based guests.

    description This update for kvm fixes the following issues : Security issues fixed : CVE-2018-10839: Fixed NE2000 NIC emulation support that is vulnerable to an integer overflow, which could lead to buffer overflow issue. It could occur when receiving packets over the network. A user inside guest could use this flaw to crash the Qemu process resulting in DoS (bsc#1110910). CVE-2018-15746: Fixed qemu-seccomp.c that might allow local OS guest users to cause a denial of service (guest crash) by leveraging mishandling of the seccomp policy for threads other than the main thread (bsc#1106222). CVE-2018-17958: Fixed a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used (bsc#1111006). CVE-2018-17962: Fixed a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used (bsc#1111010). CVE-2018-17963: Fixed qemu_deliver_packet_iov in net/net.c that accepts packet sizes greater than INT_MAX, which allows attackers to cause a denial of service or possibly have unspecified other impact. (bsc#1111013) CVE-2018-18849: Fixed an out of bounds memory access issue that was found in the LSI53C895A SCSI Host Bus Adapter emulation while writing a message in lsi_do_msgin. It could occur during migration if the 'msg_len' field has an invalid value. A user/process could use this flaw to crash the Qemu process resulting in DoS (bsc#1114422). CVE-2018-18438: Fixed integer overflows because IOReadHandler and its associated functions use a signed integer data type for a size value (bnc#1112185).

    NASL id SUSE_SU-2018-3975-1.NASL
    description This update for kvm fixes the following issues : Security issues fixed : CVE-2018-10839: Fixed NE2000 NIC emulation support that is vulnerable to an integer overflow, which could lead to buffer overflow issue. It could occur when receiving packets over the network. A user inside guest could use this flaw to crash the Qemu process resulting in DoS (bsc#1110910). CVE-2018-15746: Fixed qemu-seccomp.c that might allow local OS guest users to cause a denial of service (guest crash) by leveraging mishandling of the seccomp policy for threads other than the main thread (bsc#1106222). CVE-2018-17958: Fixed a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used (bsc#1111006). CVE-2018-17962: Fixed a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used (bsc#1111010). CVE-2018-17963: Fixed qemu_deliver_packet_iov in net/net.c that accepts packet sizes greater than INT_MAX, which allows attackers to cause a denial of service or possibly have unspecified other impact. (bsc#1111013) CVE-2018-18849: Fixed an out of bounds memory access issue that was found in the LSI53C895A SCSI Host Bus Adapter emulation while writing a message in lsi_do_msgin. It could occur during migration if the 'msg_len' field has an invalid value. A user/process could use this flaw to crash the Qemu process resulting in DoS (bsc#1114422). CVE-2018-18438: Fixed integer overflows because IOReadHandler and its associated functions use a signed integer data type for a size value (bnc#1112185). Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
