Vulnerability from cvelistv5 – Published: 2021-07-12 00:00 – Updated: 2025-04-30 22:24

Summary

Node.js before 16.4.1, 14.17.2, 12.22.2 is vulnerable to an out-of-bounds read when uv__idna_toascii() is used to convert strings to ASCII. The pointer p is read and increased without checking whether it is beyond pe, with the latter holding a pointer to the end of the buffer. This can lead to information disclosures or crashes. This function can be triggered via uv_getaddrinfo().

Severity ?

No CVSS data available.

CWE
