Mcafee : Security Vulnerabilities, CVEs, (Denial of service)

Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow.

Use After Free in Remote logging (which is disabled by default) in McAfee McAfee Agent (MA) 5.x prior to 5.6.0 allows remote unauthenticated attackers to cause a Denial of Service and potentially a remote code execution via a specially crafted HTTP header sent to the logging service.

An unspecified ActiveX control in McAfee Virtual Technician (MVT) before 6.4, and ePO-MVT, allows remote attackers to execute arbitrary code or cause a denial of service (Internet Explorer crash) via a crafted web site.

Heap-based buffer overflow in the xmlStrncat function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.

McPvDrv.sys 4.6.111.0 in McAfee File Lock 5.x in McAfee Total Protection allows local users to obtain sensitive information from kernel memory or cause a denial of service (system crash) via a large VERIFY_INFORMATION.Length value in an IOCTL_DISK_VERIFY ioctl call.

The administration interface in McAfee E-Business Server 8.5.2 and earlier allows remote attackers to cause a denial of service (crash) and execute arbitrary code via a long initial authentication packet.

The xmlNextChar function in libxml2 before 2.9.4 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.

The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.

Unspecified vulnerability in McAfee Email Anti-virus (formerly WebShield SMTP) allows remote attackers to cause a denial of service via unknown vectors.

Stack-based buffer overflow in McPvDrv.sys 4.6.111.0 in McAfee File Lock 5.x in McAfee Total Protection allows attackers to cause a denial of service (system crash) via a long vault GUID in an ioctl call.

Heap-based buffer overflow in the xmlFAParsePosCharGroup function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.

Integer signedness error in the AV engine before DAT 8145, as used in McAfee LiveSafe 14.0, allows remote attackers to cause a denial of service (memory corruption and crash) via a crafted packed executable.

Privilege escalation vulnerability in Intel Security McAfee Application Control (MAC) 7.0 and 6.x versions allows attackers to cause DoS, unexpected behavior, or potentially unauthorized code execution via an unauthorized use of IOCTL call.

Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.

Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.

Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.

Unquoted service executable path in McAfee Endpoint Security (ENS) prior to 10.7.0 November 2020 Update allows local users to cause a denial of service and malicious file execution via carefully crafted and named executable files.

Privilege Escalation vulnerability in McAfee Total Protection (MTP) prior to 16.0.30 allows a local user to gain elevated privileges and perform arbitrary file deletion as the SYSTEM user potentially causing Denial of Service via manipulating Junction link, after enumerating certain files, at a specific time.

Bypass Remote Procedure call in McAfee Total Protection (MTP) prior to 16.0.30 allows a local user to gain elevated privileges and perform arbitrary file modification as the SYSTEM user potentially causing Denial of Service via executing carefully constructed malware.

Integer overflow in McAfee ePolicy Orchestrator 3.5 through 3.6.1, ProtectionPilot 1.1.1 and 1.5, and Common Management Agent (CMA) 3.5.5.438 allows remote attackers to cause a denial of service (CMA Framework service crash) and possibly execute arbitrary code via unspecified vectors.

Unspecified vulnerability in McAfee Network Data Loss Prevention (NDLP) before 9.3 allows remote attackers to obtain sensitive information, affect integrity, or cause a denial of service via unknown vectors, related to simultaneous logins.

The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages.
