Discussion

CVS Cvsbug.In Script Insecure Temporary File Creation Vulnerability

CVS creates temporary files in an insecure manner.

The vulnerability is due to the program creating temporary files with a predictable name in the '/tmp' directory.

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