CVE-2017-5885
Status: ModifiedCritical (9.8)—
Multiple integer overflows in the (1) vnc_connection_server_message and (2) vnc_color_map_set functions in gtk-vnc before 0.7.0 allow remote servers to cause a denial of service (crash) or possibly execute arbitrary code via vectors involving SetColorMapEntries, which triggers a buffer overflow.
CVSS
- Version: 3.0
- Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Base score: 9.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 4.98%
- Percentile among all scored CVEs: 92
- Score date: 10/4/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
