CVE-2006-0550

Status: ModifiedHigh (7.5)—

Buffer overflow in an unspecified Oracle Client utility might allow remote attackers to execute arbitrary code or cause a denial of service. NOTE: due to the lack of relevant details from the Oracle advisory, a separate CVE is being created since it cannot be conclusively proven that this issue has been addressed by Oracle. It is possible that this is the same issue as Oracle Vuln# DBC02 from the January 2006 CPU, in which case this would be a duplicate of CVE-2006-0283. However, there are enough inconsistencies that the mapping can not be made authoritatively.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
Base score: 7.5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 8.23%
Percentile among all scored CVEs: 95
Score date: 10/10/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
