| CVE-2021-3450 | 10 Fedoraproject, Freebsd, Mcafee and 7 more | 35 Fedora, Freebsd, Web Gateway and 32 more | 2023-08-04 | 5.8 MEDIUM | 7.4 HIGH |
| The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. If a "purpose" has been configured then there is a subsequent opportunity for checks that the certificate is a valid CA. All of the named "purpose" values implemented in libcrypto perform this check. Therefore, where a purpose is set the certificate chain will still be rejected even when the strict flag has been used. A purpose is set by default in libssl client and server certificate verification routines, but it can be overridden or removed by an application. In order to be affected, an application must explicitly set the X509_V_FLAG_X509_STRICT verification flag and either not set a purpose for the certificate verification or, in the case of TLS client or server applications, override the default purpose. OpenSSL versions 1.1.1h and newer are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1h-1.1.1j). | |||||

| Privilege escalation vulnerability in McAfee Web Gateway (MWG) prior to 9.2.8 allows an authenticated user to gain elevated privileges through the User Interface and execute commands on the appliance via incorrect improper neutralization of user input in the troubleshooting page. | |||||
| CVE-2019-9511 | 11 Apache, Apple, Canonical and 8 more | 21 Traffic Server, Mac Os X, Swiftnio and 18 more | 2022-02-22 | 7.8 HIGH | 7.5 HIGH |
| 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. | |||||
| CVE-2019-9513 | 11 Apache, Apple, Canonical and 8 more | 21 Traffic Server, Mac Os X, Swiftnio and 18 more | 2022-02-22 | 7.8 HIGH | 7.5 HIGH |
| 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. | |||||
| CVE-2021-3156 | 8 Beyondtrust, Debian, Fedoraproject and 5 more | 25 Privilege Management For Mac, Privilege Management For Unix\/linux, Debian Linux and 22 more | 2021-10-20 | 7.2 HIGH | 7.8 HIGH |
| Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character. | |||||

| McAfee Web Gateway (MWG) earlier than 7.8.2.13 is vulnerable to a remote attacker exploiting CVE-2019-9517, potentially leading to a denial of service. This affects the scanning proxies. | |||||
| CVE-2019-3643 | 1 Mcafee | 4 Active Response, Advanced Threat Defense, Enterprise Security Manager and 1 more | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| McAfee Web Gateway (MWG) earlier than 7.8.2.13 is vulnerable to a remote attacker exploiting CVE-2019-9511, potentially leading to a denial of service. This affects the scanning proxies. | |||||
| CVE-2019-9517 | 11 Apache, Apple, Canonical and 8 more | 23 Traffic Server, Mac Os X, Swiftnio and 20 more | 2021-06-06 | 7.8 HIGH | 7.5 HIGH |
| 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. | |||||
| CVE-2019-9518 | 10 Apache, Apple, Canonical and 7 more | 19 Traffic Server, Mac Os X, Swiftnio and 16 more | 2021-05-27 | 7.8 HIGH | 7.5 HIGH |
| 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. | |||||
| CVE-2019-9514 | 12 Apache, Apple, Canonical and 9 more | 29 Traffic Server, Mac Os X, Swiftnio and 26 more | 2020-12-09 | 7.8 HIGH | 7.5 HIGH |
| 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. | |||||
| CVE-2019-9515 | 11 Apache, Apple, Canonical and 8 more | 23 Traffic Server, Mac Os X, Swiftnio and 20 more | 2020-10-22 | 7.8 HIGH | 7.5 HIGH |
| 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. | |||||
| CVE-2017-1000366 | 8 Debian, Gnu, Mcafee and 5 more | 20 Debian Linux, Glibc, Web Gateway and 17 more | 2020-10-15 | 7.2 HIGH | 7.8 HIGH |
| glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier. | |||||
