jackson-databind: improper polymorphic deserialization of types from Jodd-db library

An issue was discovered in FasterXML jackson-databind prior to 2.7.9.4, 2.8.11.2, and 2.9.6. When Default Typing is enabled (either globally or for a specific property), the service has the Jodd-db jar (for database access for the Jodd framework) in the classpath, and an attacker can provide an LDAP service to access, it is possible to make the service execute a malicious payload.

jackson-databind: Potential information exfiltration with default typing, serialization gadget from MyBatis

An issue was discovered in FasterXML jackson-databind 2.0.0 through 2.9.5. Use of Jackson default typing along with a gadget class from iBatis allows exfiltration of content. Fixed in 2.7.9.4, 2.8.11.2, and 2.9.6.

libarchive: Improper input validation in WARC parser resulting in a denial of service

libarchive version commit 9693801580c0cf7c70e862d305270a16b52826a7 onwards (release v3.2.0 onwards) contains a CWE-20: Improper Input Validation vulnerability in WARC parser - libarchive/archive_read_support_format_warc.c, _warc_read() that can result in DoS - quasi-infinite run time and disk usage from tiny file. This attack appear to be exploitable via the victim must open a specially crafted WARC file.

python: Command injection in the shutil module

Python Software Foundation Python (CPython) version 2.7 contains a CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in shutil module (make_archive function) that can result in Denial of service, Information gain via injection of arbitrary files on the system or entire drive. This attack appear to be exploitable via Passage of unfiltered user input to the function. This vulnerability appears to have been fixed in after commit add531a1e55b0a739b0f42582f1c9747e5649ace.

python: Heap-Buffer-Overflow and Heap-Use-After-Free in Objects/fileobject.c

Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. So when a large amount of data is being processed, it is very easy to cause memory corruption using a Heap-Buffer-Overflow. As for the Use-After-Free, Thread3->Malloc->Thread1->Free's->Thread2-Re-uses-Free'd Memory. The PSRT has stated that this is not a security vulnerability due to the fact that the attacker must be able to run code, however in some situations, such as function as a service, this vulnerability can potentially be used by an attacker to violate a trust boundary, as such the DWF feels this issue deserves a CVE.

expat: Inifinite loop due to invalid XML in external entity

XML External Entity vulnerability in libexpat 2.2.0 and earlier (Expat XML Parser Library) allows attackers to put the parser in an infinite loop using a malformed external entity definition from an external DTD.

XStream: DoS when unmarshalling void type

XStream through 1.4.9, when a certain denyTypes workaround is not used, mishandles attempts to create an instance of the primitive type 'void' during unmarshalling, leading to a remote application crash, as demonstrated by an xstream.fromXML("<void/>") call.

python: Integer overflow in PyString_DecodeEscape results in heap-base buffer overflow

CPython (aka Python) up to 2.7.13 is vulnerable to an integer overflow in the PyString_DecodeEscape function in stringobject.c, resulting in heap-based buffer overflow (and possible arbitrary code execution)

firefox: Possible integer overflow to fix inside XML_Parse in Expat

An integer overflow during the parsing of XML using the Expat library. This vulnerability affects Firefox < 50.

expat: Undefined behavior and pointer overflows

The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.

XStream: enabled processing of external entities

Multiple XML external entity (XXE) vulnerabilities in the (1) Dom4JDriver, (2) DomDriver, (3) JDomDriver, (4) JDom2Driver, (5) SjsxpDriver, (6) StandardStaxDriver, and (7) WstxDriver drivers in XStream before 1.4.9 allow remote attackers to read arbitrary files via a crafted XML document.

expat: Out-of-bounds heap read on crafted input causing crash

Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow.

The send package before 0.11.1 for Node.js allows attackers to obtain the root path via unspecified vectors.

XStream: remote code execution due to insecure XML deserialization

Xstream API versions up to 1.4.6 and version 1.4.10, if the security framework has not been initialized, may allow a remote attacker to run arbitrary shell commands by manipulating the processed input stream when unmarshaling XML or any supported format. e.g. JSON.

openstack-mistral: mistral: OS command injection via unvalidated proxy_command in std.ssh_proxied action

In OpenStack Mistral through 23.0.0, the std.ssh_proxied action passes a caller-supplied proxy_command value directly to paramiko.ProxyCommand() before any SSH connection to a gateway or target host is attempted. An authenticated project member can use the standard action-execution API to submit an arbitrary local command as proxy_command; paramiko starts that command as a subprocess on the executor host under the executor's own service account, independent of whether the SSH connection itself ever succeeds. Only Mistral deployments that permit the std.ssh_proxied action, the default configuration, are affected.

Uncontrolled recursion in DCMTK JSON reader allows denial of service

Uncontrolled mutual recursion between DcmJSONReader::parseDataSet(), DcmJSONReader::parseElement() and DcmJSONReader::parseSequence() in dcmdata/libsrc/dcjsonrd.cc of OFFIS DCMTK 3.7.0 allows an attacker to cause a denial of service (stack exhaustion and process crash) via a crafted DICOM JSON document with deeply nested sequence (SQ) values. The json2dcm tool and any service that converts untrusted DICOM JSON (for example, DICOMweb payloads) with this reader are affected. The issue is fixed in commit cf955e64c35a1e07ba10698f639d5dcdec53b9d7.

Uncontrolled recursion in DCMTK xml2dcm allows denial of service

Uncontrolled mutual recursion between DcmXMLParseHelper::parseDataSet() and DcmXMLParseHelper::parseSequence() in the XML-to-DICOM converter (dcmdata/libdcxml/xml2dcm.cc) of OFFIS DCMTK 3.7.0 allows an attacker to cause a denial of service (stack exhaustion and process crash) via a crafted XML file with deeply nested sequence and item elements. The xml2dcm tool and any service that converts untrusted XML to DICOM with this code are affected. The issue is fixed in commit 87f256d73e30656a822bf7d76d1cf1d9bb693954.

Uncontrolled recursion in DCMTK DICOMDIR parsing allows denial of service

Uncontrolled recursion in DcmDicomDir::moveRecordToTree() in dcmdata/libsrc/dcdicdir.cc of OFFIS DCMTK 3.7.0 allows an attacker to cause a denial of service (stack exhaustion and process crash) via a crafted DICOMDIR file with a deeply chained sequence of directory records linked through the Offset of Referenced Lower-Level Directory Entity attribute. Any application that opens the DICOMDIR is affected, including dcmgpdir and media viewers built on DCMTK. The issue is fixed in commit ca761f7f3dcaaddaa95be87cf5d736138d7c3a9f.

Heap out-of-bounds read in DCMTK RLE decodeFrame()

A heap-based out-of-bounds read in DcmRLECodecDecoder::decodeFrame() in dcmdata/libsrc/dcrleccd.cc of OFFIS DCMTK 3.7.0 allows an attacker to read up to 63 bytes of adjacent heap memory, or cause a crash, via a crafted RLE Lossless DICOM file whose pixel data fragment is shorter than the 64-byte RLE header. The function copies 64 bytes without checking the fragment length, a check that the sibling function decode() already performs. Applications that decode RLE images frame by frame (for example, through DcmPixelData::getUncompressedFrame()) are affected. The dcmdrle command-line tool uses decode() and is not affected. The issue is fixed in commit 45469f3c30037e9c7159290e4bb74cd7b3b9ef1d.
