Description

The remote host is affected by the vulnerability described in GLSA-202401-23 (libuv: Buffer Overread)

 - 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(). (CVE-2021-22918)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

All libuv users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=dev-libs/libuv-1.41.1
