CVE-2023-31418 1 Elastic 2 Elastic Cloud Enterprise, Elasticsearch 2023-11-30 N/A 7.5 HIGH
An issue has been identified with how Elasticsearch handled incoming requests on the HTTP layer. An unauthenticated user could force an Elasticsearch node to exit with an OutOfMemory error by sending a moderate number of malformed HTTP requests. The issue was identified by Elastic Engineering and we have no indication that the issue is known or that it is being exploited in the wild.
CVE-2023-33202 1 Bouncycastle 1 Bouncy Castle For Java 2023-11-30 N/A 5.5 MEDIUM
Bouncy Castle for Java before 1.73 contains a potential Denial of Service (DoS) issue within the Bouncy Castle org.bouncycastle.openssl.PEMParser class. This class parses OpenSSL PEM encoded streams containing X.509 certificates, PKCS8 encoded keys, and PKCS7 objects. Parsing a file that has crafted ASN.1 data through the PEMParser causes an OutOfMemoryError, which can enable a denial of service attack.
CVE-2023-6277 3 Fedoraproject, Libtiff, Redhat 3 Fedora, Libtiff, Enterprise Linux 2023-11-30 N/A 6.5 MEDIUM
An out-of-memory flaw was found in libtiff. Passing a crafted tiff file to TIFFOpen() API may allow a remote attacker to cause a denial of service via a craft input with size smaller than 379 KB.
CVE-2023-39325 2 Fedoraproject, Golang 3 Fedora, Go, Http2 2023-11-29 N/A 7.5 HIGH
A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the package; see the Server.MaxConcurrentStreams setting and the ConfigureServer function.
CVE-2023-32611 1 Gnome 1 Glib 2023-11-27 N/A 5.5 MEDIUM
A flaw was found in GLib. GVariant deserialization is vulnerable to a slowdown issue where a crafted GVariant can cause excessive processing, leading to denial of service.
CVE-2023-29499 1 Gnome 1 Glib 2023-11-27 N/A 7.5 HIGH
A flaw was found in GLib. GVariant deserialization fails to validate that the input conforms to the expected format, leading to denial of service.
CVE-2020-27827 5 Fedoraproject, Lldpd Project, Openvswitch and 2 more 27 Fedora, Lldpd, Openvswitch and 24 more 2023-11-26 7.1 HIGH 7.5 HIGH
A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-35498 3 Debian, Fedoraproject, Openvswitch 3 Debian Linux, Fedora, Openvswitch 2023-11-26 7.8 HIGH 7.5 HIGH
A vulnerability was found in openvswitch. A limitation in the implementation of userspace packet parsing can allow a malicious user to send a specially crafted packet causing the resulting megaflow in the kernel to be too wide, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2023-24534 1 Golang 1 Go 2023-11-25 N/A 7.5 HIGH
HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service. Certain unusual patterns of input data can cause the common function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold the parsed headers. An attacker can exploit this behavior to cause an HTTP server to allocate large amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service. With fix, header parsing now correctly allocates only the memory required to hold parsed headers.
CVE-2022-41724 1 Golang 1 Go 2023-11-25 N/A 7.5 HIGH
Large handshake records may cause panics in crypto/tls. Both clients and servers may send large TLS handshake records which cause servers and clients, respectively, to panic when attempting to construct responses. This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert).
CVE-2023-44487 30 Akka, Amazon, Apache and 27 more 126 Http Server, Opensearch Data Prepper, Apisix and 123 more 2023-11-25 N/A 7.5 HIGH
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
CVE-2023-29409 1 Golang 1 Go 2023-11-25 N/A 5.3 MEDIUM
Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so causing breakage here in the interests of increasing the default safety of users of crypto/tls seems reasonable.
CVE-2023-4162 1 Brocade 1 Fabric Operating System 2023-11-24 N/A 4.4 MEDIUM
A segmentation fault can occur in Brocade Fabric OS after Brocade Fabric OS v9.0 and before Brocade Fabric OS v9.2.0a through the passwdcfg command. This could allow an authenticated privileged user local user to crash a Brocade Fabric OS swith using the cli “passwdcfg --set -expire -minDiff“.
CVE-2023-47025 1 Free5gc 1 Free5gc 2023-11-22 N/A 5.5 MEDIUM
An issue in Free5gc v.3.3.0 allows a local attacker to cause a denial of service via the free5gc-compose component.
CVE-2023-25949 3 Intel, Linux, Microsoft 3 Aptio V Uefi Firmware Integrator Tools, Linux Kernel, Windows 2023-11-20 N/A 5.5 MEDIUM
Uncontrolled resource consumption in some Intel(R) Aptio* V UEFI Firmware Integrator Tools may allow an authenticated user to potentially enable denial of service via local access.
CVE-2023-36042 1 Microsoft 2 Visual Studio 2019, Visual Studio 2022 2023-11-20 N/A 5.5 MEDIUM
Visual Studio Denial of Service Vulnerability
CVE-2023-34462 1 Netty 1 Netty 2023-11-18 N/A 6.5 MEDIUM
Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. The `SniHandler` can allocate up to 16MB of heap for each channel during the TLS handshake. When the handler or the channel does not have an idle timeout, it can be used to make a TCP server using the `SniHandler` to allocate 16MB of heap. The `SniHandler` class is a handler that waits for the TLS handshake to configure a `SslHandler` according to the indicated server name by the `ClientHello` record. For this matter it allocates a `ByteBuf` using the value defined in the `ClientHello` record. Normally the value of the packet should be smaller than the handshake packet but there are not checks done here and the way the code is written, it is possible to craft a packet that makes the `SslClientHelloHandler`. This vulnerability has been fixed in version 4.1.94.Final.
CVE-2019-16892 1 Rubyzip Project 1 Rubyzip 2023-11-16 7.1 HIGH 5.5 MEDIUM
In Rubyzip before 1.3.0, a crafted ZIP file can bypass application checks on ZIP entry sizes because data about the uncompressed size can be spoofed. This allows attackers to cause a denial of service (disk consumption).
CVE-2023-36478 2 Eclipse, Jenkins 2 Jetty, Jenkins 2023-11-16 N/A 7.5 HIGH
Eclipse Jetty provides a web server and servlet container. In versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in `MetaDataBuilder.checkSize` allows for HTTP/2 HPACK header values to exceed their size limit. `` determines if a header name or value exceeds the size limit, and throws an exception if the limit is exceeded. However, when length is very large and huffman is true, the multiplication by 4 in line 295 will overflow, and length will become negative. `(_size+length)` will now be negative, and the check on line 296 will not be triggered. Furthermore, `MetaDataBuilder.checkSize` allows for user-entered HPACK header value sizes to be negative, potentially leading to a very large buffer allocation later on when the user-entered size is multiplied by 2. This means that if a user provides a negative length value (or, more precisely, a length value which, when multiplied by the 4/3 fudge factor, is negative), and this length value is a very large positive number when multiplied by 2, then the user can cause a very large buffer to be allocated on the server. Users of HTTP/2 can be impacted by a remote denial of service attack. The issue has been fixed in versions 11.0.16, 10.0.16, and 9.4.53. There are no known workarounds.
CVE-2023-35767 1 Perforce 1 Helix Core 2023-11-15 N/A 7.5 HIGH
In Helix Core versions prior to 2023.2, an unauthenticated remote Denial of Service (DoS) via the shutdown function was identified. Reported by Jason Geffner.
