4.6
MEDIUM · CVSS 2.0 · EPSS 0.8% (pctl 55)
Patch early
A public exploit exists.
Description
The convert-fcrontab program in fcron 3.0.0 might allow local users to gain privileges via a long command-line argument, which causes Linux glibc to report heap memory corruption, possibly because a strcpy in the strdup2 function can "overwrite some data."
