AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A NULL pointer dereference in YottaDB's trip_gen function allows attackers to crash the application via crafted input.
Vulnerability
A NULL pointer dereference vulnerability exists in the trip_gen function within sr_port/emit_code.c of YottaDB through version r1.32 and V7.0-000. The lack of proper NULL checks allows an attacker to trigger a crash by providing input that leads to dereferencing a NULL pointer [1].
Exploitation
An attacker can exploit this vulnerability by supplying specially crafted input to the YottaDB application. No authentication or special privileges are required; the attacker only needs to be able to send data that reaches the vulnerable code path. The exact sequence involves triggering the trip_gen function with a NULL pointer, causing a segmentation fault [1].
Impact
Successful exploitation results in a denial of service (DoS) by crashing the application. The attacker gains no code execution or data access; the impact is limited to application termination [1].
Mitigation
The issue is fixed in YottaDB release r1.34, which includes patches for 40 bugs discovered through fuzz testing [1]. Users should upgrade to r1.34 or later. No workaround is available for affected versions.
