In FreeRDP after 1.0 and before 2.0.0, there is a stream out-of-bounds seek in update_read_synchronize that could lead to a later out-of-bounds read.
CVE-2020-11046
This medium-severity CVE scores 5.5 under NVD CVSS v3. EPSS exploit probability: 1.3%, top 32% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
