Title

PHP GD Graphics Library拒绝服务漏洞

Description

PHP（PHP：Hypertext Preprocessor，PHP：超文本预处理器）是PHP Group和开放源代码社区共同维护的一种开源的通用计算机脚本语言。该语言支持多重语法、支持多数据库及操作系统和支持C、C++进行程序扩展等。GD Graphics Library（又名libgd或libgd2）是美国软件开发者Thomas Boutell所研发的一个开源的用于动态创建图像的库，它支持创建图表、图形和缩略图等。 PHP 5.6.12之前版本中使用的GD Graphics Library 2.2.0之前版本中的gd_interpolation.c文件中的‘gdImageScaleTwoPass’函数存在拒绝服务漏洞，该漏洞源于程序使用不一致的分配和释放方法。远程攻击者可借助特制的调用利用该漏洞造成拒绝服务（内存消耗）。

CVE-2015-8877 (GCVE-0-2015-8877)

Vulnerability from cvelistv5 – Published: 2016-05-22 01:00 – Updated: 2024-08-06 08:29

Summary

The gdImageScaleTwoPass function in gd_interpolation.c in the GD Graphics Library (aka libgd) before 2.2.0, as used in PHP before 5.6.12, uses inconsistent allocate and free approaches, which allows remote attackers to cause a denial of service (memory consumption) via a crafted call, as demonstrated by a call to the PHP imagescale function.

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.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
