CVE-2019-12068

Disclosure Date: September 24, 2019 •
CVE-2019-12068 CVSS v3 Base Score: 3.8
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8~deb10u1, 1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12 (fixed), when executing script in lsi_execute_script(), the LSI scsi adapter emulator advances ’s->dsp’ index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well.
