CyberRota Analysis
AI-GeneratedTimescaleDB versions up to 2.29.1 are vulnerable to an out-of-bounds read due to improper validation in the Dictionary compression reverse row iterator, allowing attackers with DML access to craft malicious data and execute reverse-order scans. This vulnerability can lead to the disclosure of sensitive backend memory, including shared buffer pool contents, bypassing SQL access controls. Organizations using affected versions should prioritize patching to mitigate the risk of data exposure.

Original NVD Description
TimescaleDB through 2.29.1, fixed in commit 517c13e, contains an out-of-bounds read in the Dictionary compression reverse row iterator (tsl/src/compression/algorithms/dictionary.c). The forward path validates the decoded index; the reverse path uses an assertion compiled out of release builds, leaving the 64-bit Simple8b index unvalidated and the read offset attacker-controlled. Attackers with DML access to a physical compressed relation can store a crafted datum and run a reverse-order scan. With a pass-by-value column type the out-of-bounds Datum is returned to the client as a normal column value, disclosing backend memory including the shared buffer pool, which SQL access control does not cover.
