Alpine: postgresql12: security update to 12.17-r0
high Tenable Cloud Security Plugin ID 408027
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive
information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling
'unknown'-type values from string literals without type designation can disclose bytes, potentially
revealing notable and confidential information. This issue exists due to excessive data output in
aggregate function calls, enabling remote users to read some portion of system memory. (CVE-2023-5868)
- 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. (CVE-2023-5869)
- A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers,
including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful
exploitation requires a non-core extension with a less-resilient background worker and would affect that
specific background worker only. This issue may allow a remote high privileged user to launch a denial of
service (DoS) attack. (CVE-2023-5870)
