Discussion

MailScanner Multiple Insecure Temporary File Creation Vulnerabilities

Multiple MailScanner scripts create temporary files in an insecure manner.

An attacker with local access could perform symbolic-link attacks, overwriting arbitrary files in the context of an 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.

MailScanner versions prior to 4.74.7-2 are affected.
