curl: IDN decoding inserts authority delimiters and can redirect proxy CONNECT to a different host

IDN decoding can insert authority delimiters: CURLUPUNYCODE output does not round-trip and proxy requests carry an ambiguous authority Summary libcurl's IDN decoder accepts a hostname containing U+FF20 FULLWIDTH COMMERCIAL AT ＠. libidn2's TR46 transitional fallback converts it to ASCII @...

Important: perl-Net-IDN-Encode

Issue Overview: Net::IDN::Punycode versions before 2.590 for Perl allow an out-of-bounds read via integer overflow of the delta accumulator in encodepunycode. The XS backend keeps the punycode delta, and the digit index derived from it, in a signed int. The accumulation delta += m-n h+1 has no...

CVE-2026-87078

A memory leak flaw was found in the XS backend of the Perl Net::IDN::Punycode module part of the Net-IDN-Encode distribution. The decodepunycode function allocates a scalar output buffer before validating the Punycode input. The buffer is released only on the success path, so each of the three...

CVE-2026-19954

Net::Whois::Raw versions before 2.99044 for Perl ship a pwhois command-line tool that queries WHOIS for the wrong domain for unicode domain names. pwhois encodes each non-ASCII label directly using Net::IDN::Punycode and prepends xn--. Apart from lowercasing ASCII and Cyrillic letters, it skips t...

fast-uri: fast-uri: Host confusion via skipped IDN canonicalization

A flaw was found in fast-uri, a URI parser for Node.js. This vulnerability arises because the parser fails to consistently convert internationalized domain names IDN to their standard ASCII form when processing scheme-relative references. This inconsistency can lead to host confusion, where an...

CVE-2026-74765

A flaw was found in Net::IDN::Punycode. An integer overflow vulnerability in the encodepunycode function, specifically within the XS backend, allows a remote attacker to cause an out-of-bounds read. By supplying a specially crafted string, an attacker can trigger the overflow, leading to either t...

CVE-2026-100891

A flaw was found in OpenDMARC. An encoding error in the Internationalized Domain Name IDN handler within the opendmarcpolicyquerydmarc function can cause domain name queries to fail or process incorrectly. A remote attacker could exploit this vulnerability by submitting specially crafted domain...

CVE-2016-15059

A flaw was found in Net::IDN::Punycode. An attacker can supply a specially crafted string which, when encoded by the XS backend, can lead to unchecked writes past the output buffer. This heap buffer overflow can corrupt the heap, potentially leading to arbitrary code execution or denial of servic...

Linux Distros Unpatched Vulnerability : CVE-2016-15059

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Net::IDN::Punycode versions before 2.301 for Perl allow a heap buffer overflow via unchecked writes past the output buffer in encodepunycode. The XS backend...

DEBIAN-CVE-2026-87080

Net::IDN::Punycode::PP versions before 2.590 for Perl decode a truncated label to a name containing a character it never encoded in decodepunycode. The pure-Perl decoder reads one digit at a time with four-argument substr and tests the result with defined to detect the end of the input. substr on...

DEBIAN-CVE-2026-87078

Net::IDN::Punycode versions from 2.302 before 2.590 for Perl leak the output buffer on every rejected label in decodepunycode. The XS backend allocates the scalar it returns before it validates the input, sizing the buffer at twice the input length. The scalar is released only on the success path...
