Alpine: multiple qemu packages: security update to 5.1.0-r1

medium Tenable Cloud Security Plugin ID 406788

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI device emulation support. It
could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in
hw/sd/sdhci.c. A guest user or process could use this flaw to crash the QEMU process on the host,
resulting in a denial of service condition, or potentially execute arbitrary code with privileges of the
QEMU process on the host. (CVE-2020-17380)

- In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame
count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation.
(CVE-2020-13361)

- In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a
crafted reply_queue_head field from a guest OS user. (CVE-2020-13362)

- 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)

- hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This
occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or
process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or
potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555.
(CVE-2020-15863)
