NewStart CGSL MAIN 4.05 : qemu-kvm Multiple Vulnerabilities (NS-SA-2020-0049)

high Nessus Plugin ID 140275

Language:

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 4.05, has qemu-kvm 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)

 - ip_reass in ip_input.c in libslirp 4.0.0 has a heap-based buffer overflow via a large packet because it mishandles a case involving the first fragment. (CVE-2019-14378)

 - In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c misuses snprintf return values, leading to a buffer overflow in later code. (CVE-2020-8608)

 - tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC. This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code. (CVE-2020-7039)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL qemu-kvm packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
