CWE-125

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.

A vulnerability in ClamAV versions prior to 0.100.2 could allow an attacker to cause a denial of service (DoS) condition. The vulnerability is due to an error related to the MEW unpacker within the “unmew11()” function (libclamav/mew.c), which can be exploited to trigger an invalid read memory access via a specially crafted EXE file.

** DISPUTED ** The libfsclfs_block_read function in libfsclfs_block.c in libfsclfs before 2018-07-25 allows remote attackers to cause a heap-based buffer over-read via a crafted clfs file. NOTE: the vendor has disputed this as described in the GitHub issue comments.

** DISPUTED ** The libesedb_page_read_values function in libesedb_page.c in libesedb through 2018-04-01 allows remote attackers to cause a heap-based buffer over-read via a crafted esedb file. NOTE: the vendor has disputed this as described in the GitHub issue comments.

** DISPUTED ** The libesedb_page_read_tags function in libesedb_page.c in libesedb through 2018-04-01 allows remote attackers to cause a heap-based buffer over-read via a crafted esedb file. NOTE: the vendor has disputed this as described in the GitHub issue comments.
