AV:L/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions fcron version 3.0.0

Description The issue is related to the convert-fcrontab program in fcron, where a long command-line argument can cause Linux glibc to report heap memory corruption. This might be due to a strcpy in the strdup2 function overwriting some data, potentially allowing local users to gain privileges.

Recommendations For fcron version 3.0.0, consider restricting access to the convert-fcrontab program until a fix is available, to minimize the risk of exploitation.
