This would allow an attacker in position of man-in-the-middle to send a + NXDOMAIN answer for a name that does exist, bypassing DNSSEC validation.</p> + <p>CVE-2020-10030: An issue has been found in PowerDNS Authoritative Server allowing an attacker + with enough privileges to change the system's hostname to cause disclosure of uninitialized memory + content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does + not null-terminate the returned string if the hostname is larger than the supplied buffer. Linux + systems are not affected because the buffer is always large enough. OpenBSD systems are not affected + because the returned hostname is always null-terminated. Under some conditions this issue can lead + to the writing of one null-byte out-of-bounds on the stack, causing a denial of service or possibly + arbitrary code execution.</p> + </blockquote> + </body> + </description> + <references> + <url>https://doc.powerdns.com/recursor/security-advisories/index.html</url> + <cvename>CVE-2020-10995</cvename> + <cvename>CVE-2020-12244</cvename> + <cvename>CVE-2020-10030</cvename> + </references> + <dates> + <discovery>2020-05-19</discovery> + <entry>2020-05-26</entry> + </dates> + </vuln> + <vuln vid="8db2f8b2-9e12-11ea-9e83-0cc47ac16c9d"> <topic>qmail -- 64 bit integer overflows with possible remote code execution on large SMTP requests</topic> <affects> |
