FreeBSD : elm -- remote buffer overflow in Expires header (f66e011d-13ff-11da-af41-0004614cc33d)
High Nessus Plugin ID 21539
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionUlf Harnhammar has discovered a remotely exploitable buffer overflow in Elm e-mail client when parsing the Expires header of an e-mail message :
The attacker only needs to send the victim an e-mail message. When the victim with that message in his or her inbox starts Elm or simply views the inbox in an already started copy of Elm, the buffer overflow will happen immediately. The overflow is stack-based, and it gives full control over EIP, EBP and EBX. It is caused by a bad sscanf(3) call, using a format string containing '%s' to copy from a long char array to a shorter array.
SolutionUpdate the affected package.
