Description
This security bulletin contains information about 1 security vulnerability.
1) Buffer overflow (CVE-ID: CVE-2017-16927)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
The scp_v0s_accept function in sesman/libscp/libscp_v0.c in the session manager in xrdp through 0.9.4 uses an untrusted integer as a write length, which allows local users to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted input stream.
