EulerOS 2.0 SP8 : qemu (EulerOS-SA-2020-1298)

medium Nessus Plugin ID 134790

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the qemu packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- 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)

- 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected qemu packages.
