Summary
italc vulnerabilities
Details
It was discovered that an information disclosure vulnerability existed in the LibVNCServer vendored in iTALC when sending a ServerCutText message. An attacker could possibly use this issue to expose sensitive information. (CVE-2019-15681)
It was discovered that the LibVNCServer and LibVNCClient vendored in iTALC incorrectly handled certain packet lengths. A remote attacker could possibly use this issue to obtain sensitive information, cause a denial of service, or execute arbitrary code.
