Title

bson整数溢出漏洞

Description

BSON是一款计算机数据交换格式，它是用于表示简单或复杂的数据结构、包括关联数组（也称为名称/值对）、整数索引数组和一组基本标量类型的二进制格式。 bson 0.8之前版本中存在安全漏洞，该漏洞源于对一些变量，参数和返回值，程序正确使用了int而非size_t。攻击者可借助特制的.crash文件利用该漏洞造成拒绝服务。

CVE-2020-12135 (GCVE-0-2020-12135)

Vulnerability from cvelistv5 – Published: 2020-04-24 00:31 – Updated: 2024-08-04 11:48

Summary

bson before 0.8 incorrectly uses int rather than size_t for many variables, parameters, and return values. In particular, the bson_ensure_space() parameter bytesNeeded could have an integer overflow via properly constructed bson input.

Severity

No CVSS data available.
