Alpine: multiple libxml2 packages, multiple py3-libxml2 packages: security update to 2.10.4-r0

medium Tenable Self-Hosted Container Security Plugin ID 424080

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference
 and subsequently a segfault. This occurs in xmlSchemaFixupComplexType in xmlschemas.c. (CVE-2023-28484)

 - An issue was discovered in libxml2 before 2.10.4. When hashing empty dict strings in a crafted XML
 document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic
 and memory errors, such as a double free. This behavior occurs because there is an attempt to use the
 first byte of an empty string, and any value is possible (not solely the '\0' value). (CVE-2023-29469)
