CVE-2017-15394

CVE-2017-15394 A URL spoofing flaw has been found in the extensions UI of the Chromium browser 62.0.3202.62. An IDN homograph attack demo in Chromium through extensions. 1. Load unpacked extension into Chrome 2. View extension details and observe lack of punycode Impact An attacker would leverage...

uriDeep

uriDeep Unicode encoding attacks with machine learning. Tool based on machine learning to create amazing fake domains using confusables. Some domains can deceive IDN policies Chrome & Firefox. I created the best big dictionary of confusables using neural networks. It is used in the tool and it ca...

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...

CVE-2026-74766

Net::IDN::Punycode versions from 2.301 before 2.590 for Perl allow a heap use-after-free via a decoded code point that reallocates the output buffer in decodepunycode. The XS backend inserts each decoded code point into the string buffer of the scalar it returns. decodepunycode computes the...

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...

CVE-2026-87079

Net::IDN::Punycode versions before 2.590 for Perl allow CPU exhaustion via quadratic insertion cost when decoding a long label in decodepunycode. The XS backend inserts each decoded code point into a UTF-8 buffer and finds the insertion point by scanning that buffer from the start, one character ...

CVE-2026-87081

Net::IDN::UTS46 versions before 2.590 for Perl allow CPU exhaustion via quadratic punycode encoding of an overlong label before the length check in toascii. toascii punycode encodes each label and only then applies the 63-byte DNS limit. encodepunycode in both backends follows the sample...

CVE-2026-87082

Net::IDN::Punycode versions before 2.590 for Perl hang, crash or return a wrong label via unvalidated malformed UTF-8 in encodepunycode. Neither backend checks that its input is well-formed UTF-8, so a string with the UTF-8 flag set over malformed bytes, as the :utf8 PerlIO layer produces from an...

CVE-2026-74765

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 overflow check, so...

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...

CVE-2016-15059

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 builds the encoded label in the string buffer of the scalar it returns, sized from the input length. The loop that emits the digits of each...
