Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A security flaw has been discovered in radareorg radare2 up to 6.1.6. This impacts the function r_str_word_get0set of the file libr/util/str.c. The manipulation results in integer overflow. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The patch is identified as 11ac224c0eb8d57830fccc99e1c1cd8e5d958813.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
