| Published: | 2009-07-29 | ||||||
| Updated: | 2009-07-29 | ||||||
| Summary: | NetBSD is vulnerable to a buffer overflow, caused by improper bounds checking by the libcrypto SHA256 and SHA512 hash init functions in sys/sha2.h. By sending an overly long hash value, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the affected application to crash. | ||||||
| CVSS v3 Severity: | 7.3 High (CCN CVSS v3.1 Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
