CVE-2020-11042: Canonical Ubuntu Linux

Medium severity, CVSS 5.9. EPSS: 1.8% chance of exploitation in the next 30 days.

In FreeRDP greater than 1.1 and before 2.0.0, there is an out-of-bounds read in update_read_icon_info. It allows reading a attacker-defined amount of client memory (32bit unsigned -> 4GB) to an intermediate buffer. This can be used to crash the client or store information for later retrieval. This has been patched in 2.0.0.

Affected products

• Canonical Ubuntu Linux: version 16.04 only; version 18.04 only; version 19.10 only; version 20.04 only
• Debian Debian Linux: version 9.0 only; version 10.0 only
• Freerdp Freerdp: after 1.1.0, before 2.0.0 (fixed in 2.0.0)
