openjdk-lts vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 21.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in OpenJDK.

Software Description:
- openjdk-lts: Open Source Java implementation

Details:

It was discovered that OpenJDK incorrectly limited memory when compiling a
specially crafted XPath expression. An attacker could possibly use this
issue to cause a denial of service. (CVE-2022-21426)

It was discovered that OpenJDK incorrectly handled converting certain
object arguments into their textual representations. An attacker could
possibly use this issue to cause a denial of service. (CVE-2022-21434)

It was discovered that OpenJDK incorrectly validated the encoded length of
certain object identifiers. An attacker could possibly use this issue to
cause a denial of service. (CVE-2022-21443)

It was discovered that OpenJDK incorrectly validated certain paths. An
attacker could possibly use this issue to bypass the secure validation
feature and expose sensitive information in XML files. (CVE-2022-21476)

It was discovered that OpenJDK incorrectly parsed certain URI strings. An
attacker could possibly use this issue to make applications accept
invalid of malformed URI strings. (CVE-2022-21496)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:
