[GLSA-200605-10] pdnsd: Denial of Service and potential arbitrary code execution |
||
pdnsd: Denial of Service and potential arbitrary code execution Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200605-10 (pdnsd: Denial of Service and potential arbitrary code execution) The pdnsd team has discovered an unspecified buffer overflow vulnerability. The PROTOS DNS Test Suite, by the Oulu University Secure Programming Group (OUSPG), has also revealed a memory leak error within the handling of the QTYPE and QCLASS DNS queries, leading to consumption of large amounts of memory. Impact A possible hacker can craft malicious DNS queries leading to a Denial of Service, and potentially the execution of arbitrary code. Workaround There is no known workaround at this time.
