AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
YottaDB through r1.32 and V7.0-000 crashes via divide-by-zero due to missing input validation in eb_div.
Vulnerability
A lack of input validation in calls to eb_div in sr_port/eb_muldiv.c allows a divide-by-zero error. Affected versions are YottaDB through r1.32 and GT.M V7.0-000. The issue was discovered during fuzz testing and is tracked in YottaDB/DB/YDB issue #828 [1].
Exploitation
An attacker can trigger the divide-by-zero by supplying crafted input that results in a zero divisor being passed to the eb_div function. No special privileges or authentication are required; the attacker only needs to send specially crafted data to the application.
Impact
Successful exploitation causes a crash of the application (denial of service). No data disclosure or arbitrary code execution is reported from the available references.
Mitigation
A fix is included in YottaDB r1.34, released on or around the time of this CVE publication. Users should update to r1.34 or later. No workaround is documented for unpatched versions [1].
