Discussion
wyrd Insecure Temporary File Creation Vulnerability
The 'wyrd' program is prone to a security vulnerability that allows attackers to create temporary files in an insecure manner.
An attacker with local access could potentially exploit this issue to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application.
Successfully mounting a symlink attack may allow the attacker to delete or corrupt sensitive files, which may result in a denial of service. Other attacks may also be possible.
This issue affects wyrd 1.4.3-b3; other versions may also be vulnerable.
