NewStart CGSL MAIN 6.02 : qemu Multiple Vulnerabilities (NS-SA-2022-0087)
medium Nessus Plugin ID 167503
Synopsis
The remote NewStart CGSL host is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version MAIN 6.02, has qemu packages installed that are affected by multiple vulnerabilities:- libslirp 4.0.0, as used in QEMU 4.1.0, has a use-after-free in ip_reass in ip_input.c. (CVE-2019-15890)
- An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host. (CVE-2020-14364)
- An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host. (CVE-2020-1711)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
