Apache Batik 1.13 is vulnerable to server-side request forgery, caused by improper input validation by the NodePickerPanel. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests.

Apache Ant could allow a remote authenticated attacker to bypass security restrictions, caused by an insecure temporary file flaw. By sending a specially-crafted request, an attacker could exploit this vulnerability to inject modified source files into the build process.

In kernel/bpf/hashtab.c in the Linux kernel through 5.13.8, there is an integer overflow and out-of-bounds write when many elements are placed in a single bucket. NOTE: exploitation might be impractical without the CAPSYSADMIN capability.

A flaw was found in Python. The built-in modules httplib and http.client (included in Python 2 and Python 3, respectively) do not properly validate CRLF sequences in the HTTP request method, potentially allowing manipulation to the request by injecting additional HTTP headers. The highest threat from this vulnerability is to confidentiality and integrity.

A flaw was found in xstream, a simple library used to serialize objects to XML and back again. This flaw allows a remote attacker to load and execute arbitrary code from a remote host by manipulating the processed input stream. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

A flaw was found in xstream, a simple library used to serialize objects to XML and back again. This flaw allows a remote attacker to request data from internal resources that are not publicly available by manipulating the processed input stream with Java runtime versions 14 to 8. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Impact The vulnerability may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.

Patches If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.17.

Workarounds See workarounds for the different versions covering all CVEs.

Impact The vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream.

Patches If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.15.

Workarounds The reported vulnerability does not exist running Java 15 or higher.

No user is affected, who followed the recommendation to setup XStream's Security Framework with a whitelist! Anyone relying on XStream's default blacklist can immediately switch to a whilelist for the allowed types to avoid the vulnerability.

Users of XStream 1.4.14 or below who still insist to use XStream default blacklist - despite that clear recommendation - can use a workaround depending on their version in use.

Users of XStream 1.4.14 can simply add two lines to XStream's setup code: Java xstream.denyTypes(new String[]{ "jdk.nashorn.internal.objects.NativeString" }); xstream.denyTypesByRegExp(new String[]{ ".\\.ReadAllStream\\$FileStream" });

Users of XStream 1.4.14 to 1.4.13 can simply add three lines to XStream's setup code: Java xstream.denyTypes(new String[]{ "javax.imageio.ImageIO$ContainsFilter", "jdk.nashorn.internal.objects.NativeString" }); xstream.denyTypes(new Class[]{ java.lang.ProcessBuilder.class }); xstream.denyTypesByRegExp(new String[]{ ".\\.ReadAllStream\\$FileStream" }); Users of XStream 1.4.12 to 1.4.7 who want to use XStream with a black list will have to setup such a list from scratch and deny at least the following types: javax.imageio.ImageIO$ContainsFilter, java.beans.EventHandler, java.lang.ProcessBuilder, jdk.nashorn.internal.objects.NativeString.class, java.lang.Void and void and deny several types by name pattern. Java xstream.denyTypes(new String[]{ "javax.imageio.ImageIO$ContainsFilter", "jdk.nashorn.internal.objects.NativeString" }); xstream.denyTypes(new Class[]{ java.lang.ProcessBuilder.class, "jdk.nashorn.internal.objects.NativeString", java.beans.EventHandler.class, java.lang.ProcessBuilder.class, java.lang.Void.class, void.class }); xstream.denyTypesByRegExp(new String[]{ ".\\$LazyIterator", "javax\\.crypto\\..", ".\\.ReadAllStream\\$FileStream" }); Users of XStream 1.4.6 or below can register an own converter to prevent the unmarshalling of the currently know critical types of the Java runtime. It is in fact an updated version of the workaround for CVE-2013-7285: Java xstream.registerConverter(new Converter() { public boolean canConvert(Class type) { return type != null && (type == java.beans.EventHandler.class || type == java.lang.ProcessBuilder.class || type.getName().equals("javax.imageio.ImageIO$ContainsFilter") || type.getName().equals("jdk.nashorn.internal.objects.NativeString") || type == java.lang.Void.class || void.class || Proxy.isProxy(type)) || type.getName().startsWith("javax.crypto.") || type.getName().endsWith("$LazyIterator") || type.getName().endsWith(".ReadAllStream$FileStream")); }

public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) { throw new ConversionException("Unsupported type due to security reasons."); }

public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) { throw new ConversionException("Unsupported type due to security reasons."); } }, XStream.PRIORITYLOW); For more information If you have any questions or comments about this advisory: Open an issue in XStream Contact us at XStream Google Group

.NET and Visual Studio Elevation of Privilege Vulnerability

ASP.NET Core Denial of Service Vulnerability

SQLite is vulnerable to a denial of service, caused by a use-after-free in resetAccumulator in select.c. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause a denial of service.

A flaw was found in the math/big package of Go's standard library that causes a denial of service. Applications written in Go that use math/big via cryptographic packages, including crypto/rsa and crypto/x509, are vulnerable and can potentially cause panic via a crafted certificate chain. The highest threat from this vulnerability is to system availability.

A flaw was found in the Linux kernel. A use after free issue in PI futex may lead to code execution.
