Comment 2 Lubomir Kundrak 2007-08-17 09:12:34 UTC

The CVE description is wrong. This does not have any security implications, it
only causes 'c' characters passed to shell to be escaped.

Comment 4 Simo Sorce 2007-08-17 12:54:42 UTC

This is NOT a security problem (and not even a "bug"), we have already
identified this problem months ago and verified it is only a cosmetic problem.
We were not able to find out any way to misuse or any secondary effect of
escaping the "c" character as the shell will happily expand it before running
the commands.
