Updated nginx package fixes a security vulnerabilityPublication date: 29 Jun 2021
Affected Mageia releases : 7 , 8
A flaw was found in nginx. An off-by-one error while processing DNS responses allows a network attacker to write a dot character out of bounds in a heap allocated buffer which can allow overwriting the least significant byte of next heap chunk metadata likely leading to a remote code execution in certain circumstances. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability (CVE-2021-23017).
