OESA-2026-4071 strongswan security update

The strongSwan IPsec implementation supports both the IKEv1 and IKEv2 key exchange protocols in conjunction with the native NETKEY IPsec stack of the Linux kernel. Security Fixes: In the eap-mschapv2 plugin client-side in strongSwan before 6.0.3, a malicious EAP-MSCHAPv2 server can send a crafted...

Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS : strongSwan vulnerabilities (USN-8789-1)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8789-1 advisory. It was discovered that strongSwan incorrectly handled PKCS7 containers in the openssl plugin. A remote attacker could possibly us...

wildfly-elytron-realm-token: parameter injection in EAP's elytron oauth2

A flaw was found in EAP's Elytron. An EAP application whose security domain is backed by an Elytron token-realm with oauth2-introspection would allow parameter substitution due to missing URL encoding...

undertow-core: Undertow:HTTP request smuggling via oversized chunk-size bit overlap

A flaw was found in the ChunkReader component of the Undertow HTTP server, which is used by WildFly and JBoss EAP to handle chunked transfer encoding. The issue occurs because the parser uses a single internal variable to store both the remaining chunk size and state flags. By sending a specially...

openjdk-orb: unauthed class loading via IIOP in EAP

when EAP runs with -secmgr, the openjdk-orb's JDKBridge honours attacker-supplied CDR codebase URLs during object unmarshalling on :3528, allowing an unauthenticated attacker to load and instantiate arbitrary classes from a remote URL in the server JVM before EJB security interceptors run...

artemis-server: artemis-jms-client: artemis-core-client: undertow-core: wildfly-messaging-activemq-subsystem: artemis messaging handlers in Red Hat EAP permit deserialization by default

EAP's Artemis deserialization configuration permits deserialization by default. ObjectMessage.getObject uses ObjectInputStreamWithClassLoader, which implements allow-list/block-list filtering via its checkSecurity/isTrustedType method. However, by default both allow-list and block-list are empty...

undertow-core: OOM via missing limits in chunked trailer in EAP's Undertow

A flaw was found in EAP's undertow http/1.1 chunked-transfer decoder. missing limits on size and count would allow an attacker to use an unauthenticated connection to drive the JVM to an OutOfMemory error, stopping all deployments on the listener, and achieving Denial of Service...

wildfly-clustering-faces-mojarra: com.sun.faces:jsf-impl: org.glassfish:jakarta.faces: mojarra: Unauthenticated RCE in EAP JSF applications via EL injection in ui:include

A flaw was found in EAP. Any estate hosting a JSF app using the user-controlled-include pattern would permit EL injection, achieving unauthenticated RCE as the server process user...
