CVE-2009-2957
Heap-based buffer overflow in the tftp_request function in tftp.c in dnsmasq before 2.50, when --enable-tftp is used, might allow remote attackers to execute arbitrary code via a long filename in a TFTP packet, as demonstrated by a read (aka RRQ) request.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 12.7%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
