- 漏洞讨论

Redhat sysreport creates temporary files in an insecure manner. An attacker with local access could potentially exploit this issue to obtain sensitive information in the context of the affected computer.

Exploitation would most likely result in loss of confidentiality, data or a denial of service if critical files are overwritten in the attack. Other attacks may be possible as well.

- 漏洞利用

An exploit is not required.
