[Crash-utility] [PATCH] Parse two number kernel versions i.e. 3.8
Hello Dave,
A Debian user, Timo Juhani Lindfors <timo.lindfors(a)iki.fi>, reported
this issue that and delivered the patch to resolve it. The original
strcpy is being called with overlapping arguments because it is
expecting an additional version number.
