Eclipse Jetty is vulnerable to a denial of service, caused by an error related to some of the production servers spiking with CPU use. A remote attacker could exploit this vulnerability to consume CPU that remains high even without any traffic.
A flaw was found in the way the ClassFileParser class implementation in the Hotspot component of OpenJDK performed validation of inner class index values. A specially-crafted class file could cause a Java virtual machine to crash when loaded.
An unspecified vulnerability in Java SE related to the JSSE component could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors.
A flaw was found in the Serialization component of OpenJDK. A reference to an uninitialized class descriptor encountered during object stream deserialization could cause an unexpected exception to be raised when processing an untrusted serialized input.
A flaw was found in the Nashorn JavaScript engine in the Scripting component of OpenJDK. The state machine of the regular expression Parser did not correctly handle empty string nodes in certain cases, which could cause an unexpected exception to be raised when processing a specially crafted regular expression.
A flaw was found in the Nashorn JavaScript engine in the Scripting component of OpenJDK. Processing of the forward references prior to checking for regular expression syntax errors could cause an unexpected exception to be raised when processing a specially crafted regular expression.
A flaw was found in the Serialization component of OpenJDK. The invokeWriteObject() method of the ObjectStreamClass method failed to catch InstantiationError exception during object stream deserialization, which could cause an unexpected exception to be raised when processing an untrusted serialized input.
A flaw was found in the Security component of OpenJDK. It was discovered that the unmarshalKeyInfo() method of the DOMKeyInfoFactory class and the unmarshalXMLSignature() method of the DOMXMLSignatureFactory class could raise exceptions not declared as thrown by these methods when reading key info or XML signature data from XML input.
An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause no confidentiality impact, low integrity impact, and no availability impact.
An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors.
A flaw was found in the way the Libraries component of OpenJDK handled blacklists of untrusted certificates. Alternate certificate encodings were not considered, causing certain certificate fingerprints to not be blacklisted, possibly leading to untrusted certificates being accepted.
An unspecified vulnerability in Java SE related to the JNDI component could allow an unauthenticated attacker to obtain sensitive information resulting in a low confidentiality impact using unknown attack vectors.
An unspecified vulnerability in Java SE related to the Serialization component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
A flaw was found in the mysql-connector-java package. A complicated attack against the mysql Connector/J allows attackers on the local network to interfere with a user's connection, causing a denial of service of the MySQL Connectors.
Apache Log4j is vulnerable to a man-in-the-middle attack, caused by improper certificate validation with host mismatch in the SMTP appender. An attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to obtain sensitive information or further compromise the system.
drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of a concurrency use-after-free flaw after deallocating rawcmd in the rawcmdioctl function.
A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory.
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udpinput() function and could occur while processing a udp packet that is smaller than the size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0.
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the tftpinput() function and could occur while processing a udp packet that is smaller than the size of the 'tftpt' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality.
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp6input() function and could occur while processing a udp packet that is smaller than the size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0.
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the bootpinput() function and could occur while processing a udp packet that is smaller than the size of the 'bootpt' structure. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host. The highest threat from this vulnerability is to data confidentiality.
A use-after-free flaw was found in the MegaRAID emulator of QEMU. This issue occurs while processing SCSI I/O requests in the case of an error mptsasfreerequest() that does not dequeue the request object 'req' from a pending requests queue. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. Versions between 2.10.0 and 5.2.0 are potentially affected.
drivers/net/ethernet/xilinx/xilinxemaclite.c in the Linux kernel before 5.13.3 makes it easier for attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM pointer).
An unspecified vulnerability in Java SE related to the Java SE Networking component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
A flaw was discovered in the way the Libraries component of OpenJDK processed X.509 certificates. Values of Object Identifiers (OIDs) were "interned", possibly allowing a malicious X.509 certificate to trigger excessive memory usage in a Java application processing such certificate.
A flaw was found in the way the GssKrb5Base class in the Security component of OpenJDK validated properties of SASL messages included in Kerberos GSSAPI, omitting required token checks. An remote attacker with ability to manipulate network traffic between server and client using Kerberos GSSAPI could possibly perform message modification that would not be detected during message decoding.
A flaw was found in the what the BeanContextSupport class in the Serialization component of OpenJDK handled exceptions during deserialization. A specially-crafted input could cause a Java application to use an excessive amount of resources when deserialized.
A flaw was found in the Linux kernel. The generation of the device ID from the network RNG internal state is predictable. The highest threat from this vulnerability is to data confidentiality.
A flaw was found in the kernels implementation of the bluetooth HIDP (Human Interface Device Protocol). A local attacker with access permissions to the bluetooth device can issue an IOCTL which will trigger the dohidpsockioctl function in net/bluetooth/hidp/sock.c.c. This function can potentially leak potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not correctly NULL terminated.

A flaw was found in MIT krb5 1.6 or later, an authenticated kadmin user with permission to add principals to an LDAP Kerberos database can circumvent a DN containership check by supplying both a "linkdn" and "containerdn" database argument, or by supplying a DN string which is a left extension of a container DN string but is not hierarchically within the container DN.
