UBUNTU-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...
UBUNTU-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...
UBUNTU-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...
UBUNTU-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...
UBUNTU-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...
UBUNTU-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-2026-87082
The Net::IDN::Punycode Perl module (versions before 2.590 ) is vulnerable to a hang, crash, or incorrect label generation due to unvalidated malformed UTF-8 input in the encode_punycode function. The issue arises because neither backend validates well-formed UTF-8; specifically, on Perl 5.32+ , t...

CVE-2026-87081
The Net::IDN::UTS46 Perl module (versions before 2.590 ) is vulnerable to CPU exhaustion due to quadratic punycode encoding of overlong labels within the to_ascii function. The encode_punycode function, following RFC 3492, performs an outer loop for each distinct non-ASCII code point while scanni...

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 decode_punycode
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...
