There is a DOS attack vulnerability in Apache Traffic Server (ATS) 5.2.0 to 5.3.2, 6.0.0 to 6.2.0, and 7.0.0 with the TLS handshake. This issue can cause the server to coredump.

It was discovered that a programming error in the processing of HTTPS requests in the Apache Tomcat servlet and JSP engine may result in denial of service via an infinite loop. The denial of service is easily achievable as a consequence of backporting a CVE-2016-6816 fix but not backporting the fix for Tomcat bug 57544. Distributions affected by this backporting issue include Debian (before 7.0.56-3+deb8u8 and 8.0.14-1+deb8u7 in jessie) and Ubuntu.

In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a K12 file parser crash, triggered by a malformed capture file. This was addressed in wiretap/k12.c by validating the relationships between lengths and offsets.

An issue was discovered in Django 2.2 before 2.2.26, 3.2 before 3.2.11, and 4.0 before 4.0.1. UserAttributeSimilarityValidator incurred significant overhead in evaluating a submitted password that was artificially large in relation to the comparison values. In a situation where access to user registration was unrestricted, this provided a potential vector for a denial-of-service attack.

Memory leak in the dissect_dcom_ActivationProperties function in epan/dissectors/packet-dcom-sysact.c in the DCOM ISystemActivator dissector in Wireshark 1.10.x before 1.10.1 allows remote attackers to cause a denial of service (memory consumption) via crafted packets.

In Wireshark 2.2.0 to 2.2.3 and 2.0.0 to 2.0.9, the ASTERIX dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-asterix.c by changing a data type to avoid an integer overflow.

Affects ISC DHCP 4.1.0 to 4.1-ESV-R15, 4.2.0 to 4.2.8, 4.3.0 to 4.3.6. Older versions may also be affected but are well beyond their end-of-life (EOL). Releases prior to 4.1.0 have not been tested.

FORT Validator versions prior to 1.5.2 will crash if an RPKI CA publishes an X.509 EE certificate. This will lead to RTR clients such as BGP routers to lose access to the RPKI VRP data set, effectively disabling Route Origin Validation.

epan/dissectors/packet-dcom-sysact.c in the DCOM ISystemActivator dissector in Wireshark 1.10.x before 1.10.1 does not properly determine whether there is remaining packet data to process, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4.

Buffer overflow in the RTPS dissector in Wireshark 1.8.x before 1.8.10 and 1.10.x before 1.10.2 allows remote attackers to cause a denial of service (application crash) via a crafted packet.

NLnet Labs Routinator versions 0.9.0 up to and including 0.10.1, support the gzip transfer encoding when querying RRDP repositories. This encoding can be used by an RRDP repository to cause an out-of-memory crash in these versions of Routinator. RRDP uses XML which allows arbitrary amounts of white space in the encoded data. The gzip scheme compresses such white space extremely well, leading to very small compressed files that become huge when being decompressed for further processing, big enough that Routinator runs out of memory when parsing input data waiting for the next XML element.

The gmp plugin in strongSwan before 5.9.4 has a remote integer overflow via a crafted certificate with an RSASSA-PSS signature. For example, this can be triggered by an unrelated self-signed CA certificate sent by an initiator. Remote code execution cannot occur.

A flaw was found in JSS, where it did not properly free up all memory. Over time, the wasted memory builds up in the server memory, saturating the server’s RAM. This flaw allows an attacker to force the invocation of an out-of-memory process, causing a denial of service.

It was found in Undertow before 1.3.28 that with non-clean TCP close, the Websocket server gets into infinite loop on every IO thread, effectively causing DoS.

epan/dissectors/packet-gmr1_bcch.c in the GMR-1 BCCH dissector in Wireshark 1.8.x before 1.8.8 does not properly initialize memory, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

There is a possible denial of service vulnerability in Action View (Rails) <5.2.2.1, <5.1.6.2, <5.0.7.2, <4.2.11.1 where specially crafted accept headers can cause action view to consume 100% cpu and make the server unresponsive.

The http_payload_subdissector function in epan/dissectors/packet-http.c in the HTTP dissector in Wireshark 1.6.x before 1.6.16 and 1.8.x before 1.8.8 does not properly determine when to use a recursive approach, which allows remote attackers to cause a denial of service (stack consumption) via a crafted packet.
