Overview

commons-io:commons-io is a The Apache Commons IO library contains utility classes, stream implementations, file filters, file comparators, endian transformation classes, and much more.

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') through the XmlStreamReader class. An attacker can cause the application to consume excessive CPU resources by sending specially crafted XML content.

Remediation

Upgrade commons-io:commons-io to version 2.14.0 or higher.

Overview

org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the ASN1ObjectIdentifier. An attacker can cause excessive resource consumption by submitting specially crafted ASN.1 Object Identifiers, potentially leading to service disruption.

Note: This issue only applies to applications which do consume unvetted, or otherwise unvalidated, ASN.1 encodings.

Remediation

A fix was pushed into the master branch but not yet published.

Overview

org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to improper processing of large name constraint structures in PKIXCertPathReviewer. An attacker can cause excessive resource allocation by submitting specially crafted ASN.1 objects, potentially leading to service disruption.

Workaround

This vulnerability can be mitigated by limiting the size of ASN.1 objects that can be loaded from untrusted sources, thereby capping the maximum size of a Name Constraints structure.

Remediation

A fix was pushed into the master branch but not yet published.

Overview

org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Observable Discrepancy due to the timing difference between exceptions thrown when processing RSA key exchange handshakes, AKA Marvin.

Note: The implemented fix mitigates the leakage of data via the PKCS#1 interface, but does not fully alleviate the side-channel as it allows cases in which the padding check fails but the handshake succeeds.

Remediation

There is no fixed version for org.bouncycastle:bcprov-jdk15on.

Overview

org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') within the org.bouncycastle.openssl.PEMParser class. Parsing a file that has crafted ASN.1 data through the PEMParser causes an OutOfMemoryError.

Workaround

The attack can be avoided by filtering PEM requests containing EXTERNAL tagged encodings.

Remediation

There is no fixed version for org.bouncycastle:bcprov-jdk15on.

Overview

org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the solveQuadraticEquation() function used for certificate verification in ECCurve.java. Passing a large f2m parameter can cause excessive CPU consumption.

Remediation

There is no fixed version for org.bouncycastle:bcprov-jdk15on.

Overview

org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Information Exposure due to missing validation for the X.500 name of any certificate, subject, or issuer. The presence of a wild card may lead to information disclosure. This could allow a malicious user to obtain unauthorized information via blind LDAP Injection, exploring the environment and enumerating data.

Note:

The exploit depends on the structure of the target LDAP directory as well as what kind of errors are exposed to the user.

Remediation

A fix was pushed into the master branch but not yet published.
