Redhat » Enterprise Linux For Power Little Endian Eus : Security Vulnerabilities, CVEs, Published In 2023 (Overflow)

A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary bytes to memory and extensively read the server's memory.

A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution.

A vulnerability was found in WebKit. The flaw is triggered when processing maliciously crafted web content that may lead to arbitrary code execution. Improved memory handling addresses the multiple memory corruption issues.
