An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed later on, leading to DoS (segmentation fault).

The Rx parser in tcpdump before 4.9.3 has a buffer over-read in print-rx.c:rx_cache_find() and rx_cache_insert().

The BGP parser in tcpdump before 4.9.3 has a buffer over-read in print-bgp.c:bgp_capabilities_print() (BGP_CAPCODE_RESTART).

An issue was discovered in PHP 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before 7.2.1. Inappropriately parsing an HTTP response leads to a segmentation fault because http_header_value in ext/standard/http_fopen_wrapper.c can be a NULL value that is mishandled in an atoi call.

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the MMSE dissector could go into an infinite loop. This was addressed in epan/proto.c by adding offset and length validation.

A null-pointer dereference vulnerability was found in libtirpc before version 0.3.3-rc3. The return value of makefd_xprt() was not checked in all instances, which could lead to a crash when the server exhausted the maximum number of available file descriptors. A remote attacker could cause an rpc-based application to crash by flooding it with new connections.

In Apache Thrift 0.9.3 to 0.12.0, a server implemented in Go using TJSONProtocol or TSimpleJSONProtocol may panic when feed with invalid input data.

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the ASN.1 BER dissector could crash. This was addressed in epan/dissectors/packet-ber.c by ensuring that length values do not exceed the maximum signed integer.

In ng_pkt in transports/smart_pkt.c in libgit2 before 0.26.6 and 0.27.x before 0.27.4, a remote attacker can send a crafted smart-protocol "ng" packet that lacks a '\0' byte to trigger an out-of-bounds read that leads to DoS.

The read_request_line function in server/protocol.c in the Apache HTTP Server 2.4.12 does not initialize the protocol structure member, which allows remote attackers to cause a denial of service (NULL pointer dereference and process crash) by sending a request that lacks a method to an installation that enables the INCLUDES filter and has an ErrorDocument 400 directive specifying a local URI.

The LMP parser in tcpdump before 4.9.3 has a buffer over-read in print-lmp.c:lmp_print_data_link_subobjs().

Phoenix Contact FL IL 24 BK-PAC allows remote attackers to cause a denial of service (hang) via (1) unspecified manipulations as demonstrated by a Nessus scan or (2) malformed input to TCP port 502.

A vulnerability was discovered in 389-ds-base through versions 1.3.7.10, 1.3.8.8 and 1.4.0.16. The lock controlling the error log was not correctly used when re-opening the log file in log__error_emergency(). An attacker could send a flood of modifications to a very large DN, which would cause slapd to crash.

The LDP parser in tcpdump before 4.9.3 has a buffer over-read in print-ldp.c:ldp_tlv_print().

Unspecified vulnerability in the Oracle Transportation Management component in Oracle Supply Chain Products Suite 6.1, 6.2, 6.3, 6.3.1, 6.3.2, 6.3.3, 6.3.4, and 6.3.5 allows remote attackers to affect availability via unknown vectors related to Security.

A flaw in the java.math component in IBM SDK, Java Technology Edition 6.0, 7.0, and 8.0 may allow an attacker to inflict a denial-of-service attack with specially crafted String data. IBM X-Force ID: 141681.

A flaw was found in privoxy before 3.0.32. An assertion failure could be triggered with a crafted CGI request leading to server crash.

Unspecified vulnerability in the Oracle Data Integrator component in Oracle Fusion Middleware 11.1.1.3.0 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Data Quality, a different vulnerability than CVE-2014-2407, CVE-2014-2416, CVE-2014-2417, and CVE-2014-2418.

internal/XMLReader.cpp in Apache Xerces-C before 3.1.2 allows remote attackers to cause a denial of service (segmentation fault and crash) via crafted XML data.

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the HTTP2 dissector could crash. This was addressed in epan/dissectors/packet-http2.c by verifying that header data was found before proceeding to header decompression.

ARM mbed TLS before 2.1.11, before 2.7.2, and before 2.8.0 has a buffer over-read in ssl_parse_server_key_exchange() that could cause a crash on invalid input.

asn1/lpp/lpp.cnf in the LPP dissector in Wireshark 1.10.x before 1.10.12 and 1.12.x before 1.12.3 does not validate a certain index value, which allows remote attackers to cause a denial of service (out-of-bounds memory access and application crash) via a crafted packet.

Off-by-one error in the __imlib_MergeUpdate function in lib/updates.c in imlib2 before 1.4.9 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted coordinates.

Buffer underflow in the ssl_decrypt_record function in epan/dissectors/packet-ssl-utils.c in Wireshark 1.10.x before 1.10.12 and 1.12.x before 1.12.3 allows remote attackers to cause a denial of service (application crash) via a crafted packet that is improperly handled during decryption of an SSL session.

In Wireshark 2.4.0 to 2.4.5 and 2.2.0 to 2.2.13, the VLAN dissector could crash. This was addressed in epan/dissectors/packet-vlan.c by limiting VLAN tag nesting to restrict the recursion depth.

An improper handing of overflow in the UTF-8 decoder with supplementary characters can lead to an infinite loop in the decoder causing a Denial of Service. Versions Affected: Apache Tomcat 9.0.0.M9 to 9.0.7, 8.5.0 to 8.5.30, 8.0.0.RC1 to 8.0.51, and 7.0.28 to 7.0.86.

The DER parser in Suricata before 2.0.8 allows remote attackers to cause a denial of service (crash) via vectors related to SSL/TLS certificates.

A Buffer Overflow issue was discovered in Asterisk through 13.19.1, 14.x through 14.7.5, and 15.x through 15.2.1, and Certified Asterisk through 13.18-cert2. When processing a SUBSCRIBE request, the res_pjsip_pubsub module stores the accepted formats present in the Accept headers of the request. This code did not limit the number of headers it processed, despite having a fixed limit of 32. If more than 32 Accept headers were present, the code would write outside of its memory and cause a crash.

By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.18-2.4.30,2.4.33).

A flaw was found in privoxy before 3.0.32. A invalid read of size two may occur in chunked_body_is_complete() leading to denial of service.
