[SECURITY] Fedora 32 Update: pngcheck-2.4.0-7.fc32

pngcheck verifies the integrity of PNG, JNG and MNG files by checking the internal 32-bit CRCs checksums and decompressing the image data; it can optionally dump almost all of the chunk-level information in the image in human-readable form. For example, it can be used to print the basic statist i...

A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query dnsmasq checks in forward.c:reply_query() which is the forwarded query that matches the reply by only using a weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC SHA-1 when it is) this flaw allows an off-path attacker to find several different domains all having the same hash substantially reducing the number of attempts they would have to perform to forge a reply and get it accepted by dnsmasq. This is in contrast with RFC5452 which specifies that the query name is one of the attributes of a query that must be used to match a reply. This flaw could be abused to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25684 the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
