CVE-2009-2958

Publication date 2 September 2009

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The tftp_request function in tftp.c in dnsmasq before 2.50, when --enable-tftp is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a TFTP read (aka RRQ) request with a malformed blksize option.
