CVSS 3.0
9.1 criticalCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:HCVE-2019-9748
Critical (9.1) in tinysvcmdns project tinysvcmdns. EPSS 2.4% chance of exploitation in the next 30 days.
In tinysvcmdns through 2018-01-16, an mDNS server processing a crafted packet can perform arbitrary data read operations up to 16383 bytes from the start of the buffer. This can lead to a segmentation fault in uncompress_nlabel in mdns.c and a crash of the server (depending on the memory protection of the CPU and the operating system), or disclosure of memory content via error messages or a server response. NOTE: the product's web site states "This project is un-maintained, and has been since 2013. ... There are known vulnerabilities ...
