LowCVSS 3.3Exploitation Probability (EPSS)
Low risk34th percentile - higher than 34% of all known CVEs
Summary
In curl 7.65.2, an integer overflow occurs in tool_operate.c with a large retry delay value.
Risk Assessment
Theoretically could cause denial of service if the delay is misinterpreted, but practical risk is low as it requires setting a delay of weeks or longer.
Recommendation
Update curl to a newer patched version.
Original NVD description (English source)
Integer overflow vulnerability in tool_operate.c in curl 7.65.2 via a large value as the retry delay. NOTE: many parties report that this has no direct security impact on the curl user; however, it may (in theory) cause a denial of service to associated systems or networks if, for example, --retry-delay is misinterpreted as a value much smaller than what was intended. This is not especially plausible because the overflow only happens if the user was trying to specify that curl should wait weeks (or longer) before trying to recover from a transient error.
