Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities were fixed in qemu, a fast processor emulator.

CVE-2020-1983

slirp: Fix use-after-free in ip_reass().

CVE-2020-13361

es1370_transfer_audio in hw/audio/es1370.c allowed guest OS users to trigger an out-of-bounds access during an es1370_write() operation.

CVE-2020-13362

megasas_lookup_frame in hw/scsi/megasas.c had an out-of-bounds read via a crafted reply_queue_head field from a guest OS user.

CVE-2020-13765

hw/core/loader: Fix possible crash in rom_copy().

For Debian 8 'Jessie', these problems have been fixed in version 1:2.1+dfsg-12+deb8u15.

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.
