Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU25510
Risk: Medium
CVSSv3.1: 5.6 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-1711
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a boundary error in the way the iSCSI Block driver handles a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an "iscsi_co_block_status()" routine. A remote authenticated attacker can trigger heap-based buffer overflow and cause a denial of service condition or potentially execute arbitrary code with privileges of the QEMU process on the host.

2) Heap-based buffer overflow
EUVDB-ID: #VU25458
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-7039
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows an attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the tcp_emu() function in tcp_subr.c in libslirp. An attacker can issue specially crafted IRC DCC commands in EMU_IRC, trigger heap-based buffer overflow and execute arbitrary code on the target system.
