CVE-2017-9107
CVSS v3.1
7.5
High
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
adns versions prior to 1.5.2
Description:
An issue was discovered in adns where it overruns reading a buffer if a domain ends with a backslash. If the query domain ended with a backslash and
adns qf quoteok query was specified, qdparselabel would read additional bytes from the buffer and try to treat them as the escape sequence, potentially leading to a denial of service attack by crashing due to outrunning available memory.Recommendations:
For versions prior to 1.5.2, update to version 1.5.2 or later to resolve the issue. As a temporary workaround, consider avoiding the use of domains that end with a backslash until the update is applied.
