Debian DLA-2090-1 : qemu security update

medium Nessus Plugin ID 133366

Language:

Synopsis

The remote Debian host is missing a security update.

Description

tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanag es memory, as demonstrated by IRC DCC commands in EMU_IRC.
This can cause a heap-based buffer overflow or other out-of-bounds acces s which can lead to a DoS or potential execute arbitrary code.

For Debian 8 'Jessie', this problem has been fixed in version 1:2.1+dfsg-12+deb8u13.

We recommend that you upgrade your qemu packages.

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

Solution

Upgrade the affected packages.
