A server could send a SSHMSGCHANNELREQUEST packet with an exit signal message with a length of max unsigned integer value. The length would then have a value of 1 added to it and used to allocate memory causing a possible memory write out of bounds error or zero byte allocation.

A server could send a value approching unsinged int max number of keyboard prompt requests which could result in an unchecked interger overflow. The value would then be used to allocate memory causing a possible memory write out of bounds error.

A possible QBpmHandler segmentation fault on malformed BMP file. A crafted filed could cause the application to crash.

In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the ASN.1 BER and related dissectors could crash. This was addressed in epan/dissectors/packet-ber.c by preventing a buffer overflow associated with excessive digits in time values.

hw/ppc/spapr.c in QEMU through 3.1.0 allows Information Exposure because the hypervisor shares the /proc/device-tree/system-id and /proc/device-tree/model system attributes with a guest.

DISPUTED An issue was discovered in Jinja2 2.10. The fromstring function is prone to Server Side Template Injection (SSTI) where it takes the "source" parameter as a template object, renders it, and then returns it. The attacker can exploit it with {{INJECTION COMMANDS}} in a URI. NOTE: The maintainer and multiple third parties believe that this vulnerability isn't valid because users shouldn't use untrusted templates without sandboxing.

embed/ephy-web-view.c in GNOME Web (aka Epiphany) through 3.31.4 allows address bar spoofing because a page load triggered by JavaScript leads to updating an address as if it were triggered by a safer visit type (e.g., VISITLINK, VISITTYPED, VISITBOOKMARK, or VISITHOMEPAGE).

Upstream issue: https://gitlab.gnome.org/GNOME/epiphany/issues/532

Keep-alive HTTP and HTTPS connections can remain open and inactive for up to 2 minutes in Node.js 6.16.0 and earlier. Node.js 8.0.0 introduced a dedicated server.keepAliveTimeout which defaults to 5 seconds. The behavior in Node.js 6.16.0 and earlier is a potential Denial of Service (DoS) attack vector. Node.js 6.17.0 introduces server.keepAliveTimeout and the 5-second default.

All actively supported release lines are vulnerable and the severity is LOW. An attacker can cause a Denial of Service (DoS) by establishing an HTTP or HTTPS connection in keep-alive mode and by sending headers very slowly thereby keeping the connection and associated resources alive for a long period of time. Attack potential is mitigated by the use of a load balancer or other proxy layer.

A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6 and 4.10.2 are vulnerable.

A server could send a specially crafted SSH packet with a padding length value greater than the packet length. This would result in a buffer read out of bounds when decompressing the packet or result in a corrupted packet value.

An out of bounds read flaw was discovered in libssh2 before 1.8.1 in the way SFTP packets with empty payloads are parsed. A remote attacker who compromises a SSH server may be able to cause a Denial of Service or read data in the client memory.

A flaw was found in libvirtd. A null pointer in virJSONValueObjectHasKey function in util/virjson.c triggers a crash, resulting in remote denial of service via guest agent.

It was found that the forceput operator could be extracted from the DefineResource method in ghostscript before 9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER.

Openwsman, versions up to and including 2.6.9, are vulnerable to infinite loop in processconnection() when parsing specially crafted HTTP requests. A remote, unauthenticated attacker can exploit this vulnerability by sending malicious HTTP request to cause denial of service to openwsman server.

It was found that openwsman can access various secret files without having the correct privileges set. A local attacker could use this for information disclosure.

A vulnerability was found in sssd where, if a user was configured with no home directory set, sssd would return '/' (the root directory) instead of '' (the empty string / no home directory). This could impact services that restrict the user's filesystem access to within their home directory through chroot().

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Networking). Supported versions that are affected are Java SE: 7u201, 8u192 and 11.0.1; Java SE Embedded: 8u191. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.0 Base Score 3.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).

A vulnerability in the Portable Document Format (PDF) scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of proper data handling mechanisms within the device buffer while indexing remaining file data on an affected device. An attacker could exploit this vulnerability by sending crafted PDF files to an affected device. A successful exploit could allow the attacker to cause a heap buffer out-of-bounds read condition, resulting in a crash that could result in a denial of service condition on an affected device.

A vulnerability in the Object Linking & Embedding (OLE2) file scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms for OLE2 files sent an affected device. An attacker could exploit this vulnerability by sending malformed OLE2 files to the device running an affected version ClamAV Software. An exploit could allow the attacker to cause an out-of-bounds write condition, resulting in a crash that could result in a denial of service condition on an affected device.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the DCERPC SPOOLSS dissector could crash. This was addressed in epan/dissectors/packet-dcerpc-spoolss.c by adding a boundary check.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the LDSS dissector could crash. This was addressed in epan/dissectors/packet-ldss.c by handling file digests properly.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the SRVLOC dissector could crash. This was addressed in epan/dissectors/packet-srvloc.c by preventing a heap-based buffer under-read.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the GSS-API dissector could crash. This was addressed in epan/dissectors/packet-gssapi.c by ensuring that a valid dissector is called.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the DOF dissector could crash. This was addressed in epan/dissectors/packet-dof.c by properly handling generated IID and OID bytes.

In Wireshark 2.4.0 to 2.4.13, 2.6.0 to 2.6.7, and 3.0.0, the NetScaler file parser could crash. This was addressed in wiretap/netscaler.c by improving data validation.

An off-by-one read vulnerability was discovered in ImageMagick before version 7.0.7-28 in the formatIPTCfromBuffer function in coders/meta.c. A local attacker may use this flaw to read beyond the end of the buffer or to crash the program.

An issue was discovered in fs/f2fs/inline.c in the Linux kernel through 4.4. A denial of service (out-of-bounds memory access and BUG) can occur for a modified f2fs filesystem image in which an inline inode contains an invalid reserved blkaddr.

Cross-site scripting (XSS) vulnerability in the link dialogue in GUI editor in MoinMoin before 1.9.10 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
