The mcopy function in softmagic.c in file 5.x, as used in the Fileinfo component in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8, does not properly restrict a certain offset value, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string that is mishandled by a "Python script text executable" rule.
The NetKVM Windows Virtio driver allows remote attackers to cause a denial of service (guest crash) via a crafted length value in an IP packet, as demonstrated by a value that does not account for the size of the IP options.
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 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).
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.

The gmp plugin in strongSwan before 5.5.3 does not properly validate RSA public keys before calling mpz_powm_sec, which allows remote peers to cause a denial of service (floating point exception and process crash) via a crafted certificate.
In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the PacketBB dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-packetbb.c by restricting additions to the protocol tree.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is an LDSS dissector crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-ldss.c by ensuring that memory is allocated for a certain data structure.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a WSP infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-wsp.c by validating the capability length.
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a NetScaler file parser crash, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by validating the relationship between pages and records.
Dovecot before version 2.2.29 is vulnerable to a denial of service. When 'dict' passdb and userdb were used for user authentication, the username sent by the IMAP/POP3 client was sent through var_expand() to perform %variable expansion. Sending specially crafted %variable fields could result in excessive memory usage causing the process to crash (and restart), or excessive CPU usage causing all authentications to hang.
PerlRun.pm in Apache mod_perl before 1.30, and RegistryCooker.pm in mod_perl 2.x, does not properly escape PATH_INFO before use in a regular expression, which allows remote attackers to cause a denial of service (resource consumption) via a crafted URI.
LibRaw before 0.20-RC1 lacks a thumbnail size range check. This affects decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, and utils/thumb_utils.cpp. For example, malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without validating T.tlength.
Matrix Synapse before 1.20.0 erroneously permits non-standard NaN, Infinity, and -Infinity JSON values in fields of m.room.member events, allowing remote attackers to execute a denial of service attack against the federation and common Matrix clients. If such a malformed event is accepted into the room's state, the impact is long-lasting and is not fixed by an upgrade to a newer version, requiring the event to be manually redacted instead. Since events are replicated to servers of other room members, the impact is not constrained to the server of the event sender.

The mget function in softmagic.c in file 5.x, as used in the Fileinfo component in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8, does not properly maintain a certain pointer relationship, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string that is mishandled by a "Python script text executable" rule.
The Moped::BSON::ObjecId.legal? method in rubygem-moped before commit dd5a7c14b5d2e466f7875d079af71ad19774609b allows remote attackers to cause a denial of service (worker resource consumption) or perform a cross-site scripting (XSS) attack via a crafted string.
parsers.c in Privoxy before 3.0.23 allows remote attackers to cause a denial of service (invalid read and crash) via vectors related to an HTTP time header.
A flaw was found in the Red Hat Ceph Storage RGW in versions before 14.2.21. When processing a GET Request for a swift URL that ends with two slashes it can cause the rgw to crash, resulting in a denial of service. The greatest threat to the system is of availability.
epan/dissectors/packet-rdp.c in the RDP dissector in Wireshark 1.8.x before 1.8.8 does not validate return values during checks for data availability, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.
A flaw was found in privoxy before 3.0.32. A crash can occur via a crafted CGI request if Privoxy is toggled off.
A flaw was found in the way Ceph Object Gateway would process cross-origin HTTP requests if the CORS policy was set to allow origin on a bucket. A remote unauthenticated attacker could use this flaw to cause denial of service by sending a specially-crafted cross-origin HTTP request. Ceph branches 1.3.x and 2.x are affected.
In Wireshark 3.2.0 to 3.2.1, 3.0.0 to 3.0.8, and 2.6.0 to 2.6.14, the WiMax DLMAP dissector could crash. This was addressed in plugins/epan/wimax/msg_dlmap.c by validating a length field.
An issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer. On systems with memory access protections, this can result in the helper process being terminated unexpectedly. This leads to the Squid process also terminating and a denial of service for all clients using the proxy.
A flaw was found in libwebp in versions before 1.0.1. When reading a file libwebp allocates an excessive amount of memory. The highest threat from this vulnerability is to the service availability.
A vulnerability was discovered in SPICE before 0.13.90 in the server's protocol handling. An attacker able to connect to the SPICE server could send crafted messages which would cause the process to crash.
The Verify function in crypto/dsa/dsa.go in Go before 1.5.4 and 1.6.x before 1.6.1 does not properly check parameters passed to the big integer library, which might allow remote attackers to cause a denial of service (infinite loop) via a crafted public key to a program that uses HTTPS client certificates or SSH server libraries.
