CVE-2026-2474 Crypt::URandom versions from 0.41 before 0.55 for Perl is vulnerable to a heap buffer overflow in the XS function crypt_urandom_getrandom()

Crypt::URandom versions from 0.41 before 0.55 for Perl is vulnerable to a heap buffer overflow in the XS function crypturandomgetrandom. The function does not validate that the length parameter is non-negative. If a negative value e.g. -1 is supplied, the expression length + 1u causes an integer...
