SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionDrWhax reports :
So in codeconv.c there is a function for Japanese character set conversion called conv_jistoeuc(). There is no bounds checking on the output buffer, which is created on the stack with alloca() Bug can be triggered by sending an email to [email protected] or whatever.
Since my C is completely rusty, you might be able to make a better judgment on the severity of this issue. Marking critical for now.
SolutionUpdate the affected package.
