Crypt::OpenSSL::PKCS12 versions before 1.96 for Perl permits a heap OOB read in print_attribute UTF8STRING path
Vulnerability Description
Crypt::OpenSSL::PKCS12 versions before 1.96 for Perl permits a heap OOB read in print_attribute UTF8STRING path. print_attribute() copies a UTF8STRING ASN.1 attribute value into a heap buffer sized exactly to its declared length via strncpy, leaving no NUL terminator. Downstream callers run strlen() on the result and pass the inflated length to newSVpvn(), copying attacker-influenced adjacent heap bytes into a Perl scalar.

JONASBN Crypt::OpenSSL::PKCS12 缓冲区错误漏洞
Vulnerability Description
JONASBN Crypt::OpenSSL::PKCS12是JONASBN的Perl加密模块。 JONASBN Crypt::OpenSSL::PKCS12 1.96之前版本存在缓冲区错误漏洞,该漏洞源于print_attribute UTF8STRING路径存在堆越界读取,print_attribute()函数通过strncpy将UTF8STRING ASN.1属性值复制到按声明长度精确分配的堆缓冲区,未添加NUL终止符,下游调用者对结果执行strlen()并将膨胀后的长度传递给newSVpvn(),
