kernel: net: xen: Linux netback driver OOB access in hash handling (XSA-270)

An issue was discovered in xenvif_set_hash_mapping in drivers/net/xen-netback/hash.c in the Linux kernel through 4.18.1, as used in Xen through 4.11.x and other products. The Linux netback driver allows frontends to control mapping of requests to request queues. When processing a request to set or change this mapping, some input validation (e.g., for an integer overflow) was missing or flawed, leading to OOB access in hash handling. A malicious or buggy frontend may cause the (usually privileged) backend to make out of bounds memory accesses, potentially resulting in one or more of privilege escalation, Denial of Service (DoS), or information leaks.

An Out-of-Bounds Read Privilege Escalation vulnerability in Trend Micro Security 2018 (Consumer) products could allow a local attacker to escalate privileges on vulnerable installations. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit the vulnerability.

UltraVNC revision 1198 has a buffer underflow vulnerability in VNC client code, which can potentially result in code execution. This attack appears to be exploitable via network connectivity. This vulnerability has been fixed in revision 1199.
