- Summary
- CVE-2021-45955 affecting package dnsmasq for versions less than 2.89-2
- Details
-
Dnsmasq 2.86 has a heap-based buffer overflow in resizepacket (called from FuzzResizePacket and fuzzrfc1035.c) because of the lack of a proper bounds check upon pseudo header re-insertion. NOTE: the vendor's position is that CVE-2021-45951 through CVE-2021-45957 "do not represent real vulnerabilities, to the best of our knowledge." However, a contributor states that a security patch (mentioned in 016162.html) is needed
