Vulnerability Assessment Details

[GLSA-200410-02] Netpbm: Multiple temporary file issues

Vulnerability Assessment Summary
Netpbm: Multiple temporary file issues

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200410-02
(Netpbm: Multiple temporary file issues)

Utilities contained in the Netpbm package prior to the 9.25 version contain
defects in temporary file handling. They create temporary files with
predictable names without checking first that the target file doesn't
already exist.

Impact

A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When a
user or a tool calls one of the affected utilities, this would result in
file overwriting with the rights of the user running the utility.

Workaround

There is no known workaround at this time.
