A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.
IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to intercept messages and forge replies due to the exposure of sensitive information.

A flaw was found in the Linux kernel. IBM Power9 processors can speculatively operate on data stored in the L1 cache before it has been completely validated. The attack has limited access to memory and is only able to access memory normally permissible to the execution context. The highest threat from this vulnerability is to data confidentiality.
