Name of the Vulnerable Software and Affected Versions Net::IDN::UTS46 versions prior to 2.590 Description An issue exists where CPU exhaustion can occur due to quadratic punycode encoding of an overlong label. This happens because the to ascii function performs punycode encoding on each label...

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-2026-87082

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...

Linux Distros Unpatched Vulnerability : CVE-2026-74765

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 2.590 for Perl allow an out-of-bounds read via integer overflow of the delta accumulator in encodepunycode. The XS backend...

Linux Distros Unpatched Vulnerability : CVE-2026-74766

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 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...

Linux Distros Unpatched Vulnerability : CVE-2026-87079

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 2.590 for Perl allow CPU exhaustion via quadratic insertion cost when decoding a long label in decodepunycode. The XS backend...

Linux Distros Unpatched Vulnerability : CVE-2026-87081

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

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-2026-87079

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...

Linux Distros Unpatched Vulnerability : CVE-2026-87078

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 from 2.302 before 2.590 for Perl leak the output buffer on every rejected label in decodepunycode. The XS backend allocates the scal...

CVE-2016-15059: Heap-based Buffer Overflow

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...
