8th percentile - higher than 8% of all known CVEs

Summary

ExtUtils::Typemaps::STL::String versions before 1.06 for Perl may read the SV length before stringifying the argument. Due to unspecified evaluation order in C++, some compilers may evaluate SvCUR on a non-string, leading to abort or segfault.

Risk Assessment

The risk is program crash (segfault) or unexpected termination, especially when the argument is not a string (e.g., number, reference).

Recommendation

It is recommended to upgrade to version 1.06 or later, which fixes this issue.

Original NVD description (English source)

ExtUtils::Typemaps::STL::String versions before 1.06 for Perl T_STD_STRING typemap may read the SV length before stringifying the argument. The typemap uses $var = std::string( SvPV_nolen($arg), SvCUR($arg) ) However, evaluation order for C++ arguments is not specified, and some compilers may produce code that evalutes SvCUR($arg) first. When $arg is not a string (for example, an interger, number or a reference) then SvCUR will return an invalid value, and the program may abort or segfault.
