GNU A2PS fixps.in Script Insecure Temporary File Vulnerability

GNU A2PS fixps.in Script Insecure Temporary File Vulnerability

GNU a2ps is prone to a vulnerability that may allow malicious local users to corrupt files. This issue occurs because the 'fixps.in' script creates temporary files in an insecure manner, allowing symbolic-link attacks.

File corruption would occur in the context of the user running the script. It is not known if attackers could leverage this issue to elevate privileges.
