Title

PHP simplestring_addn函数整数签名漏洞

Description

PHP是广泛使用的通用目的脚本语言，特别适合于Web开发，可嵌入到HTML中。 PHP 5.5.38之前版本，5.6.24之前的5.6.x版本，7.0.9之前的7.x版本中的xmlrpc-epi/simplestring.c/simplestring_addn函数存在整数签名漏洞。远程攻击者通过xmlrpc_encode_request函数内较长的参数，利用此漏洞可造成拒绝服务（堆缓冲区溢出）。

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
