AI-Generated

TimescaleDB versions up to 2.29.1 are susceptible to an out-of-bounds read vulnerability that can be exploited by authenticated attackers with direct DML access to non-frozen physical compressed hypertables. This flaw can lead to query-result integrity failures, backend crashes, or incorrect aggregation outputs, potentially disrupting database operations. Organizations using TimescaleDB should prioritize patching to mitigate the risk of exploitation and ensure system stability.

Original NVD Description

TimescaleDB through 2.29.1, fixed in commit 517c13e, contains an out-of-bounds read vulnerability that allows authenticated attackers to cause query-result integrity failures or backend crashes by supplying a crafted Simple8b selector-11 value, which is stored in the signed int16 Arrow dictionary-index type and bypasses index validation checks in bulk text dictionary decompression. Attackers with direct DML access to a non-frozen physical compressed hypertable relation can trigger an out-of-bounds read before the base of the live offsets array through the VectorAgg single-text hashing strategy, resulting in incorrect aggregation output, backend SIGSEGV, or PostgreSQL crash recovery depending on build configuration.
