Astra Linux – Vulnerability in openjdk-11, bcel

The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode. Users are recommended to update to version 2.7.3 o...

Astra Linux – Vulnerability in bcel

Apache Commons BCEL includes several APIs that typically only allow modifying specific class characteristics. However, due to an out-of-bounds writing issue, these APIs can be used to generate arbitrary bytecode. This could lead to abuse in applications that send attacker-controllable data to tho...
