Quick assessment
Affected
Red Hat Red Hat Enterprise Linux 10
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
glib是GNOME项目的一个通用的、可移植的实用程序库。提供了许多有用的数据类型、宏、类型转换、字符串实用程序、文件实用程序、主循环抽象等。 glib存在路径遍历漏洞，该漏洞源于临时文件创建时整数溢出导致越界内存访问，可能允许攻击者通过创建符号链接执行路径遍历或访问私有临时文件内容。

Vulnerability Title
Glib: buffer under-read on glib through glib/gfileutils.c via get_tmp_file()
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in glib. An integer overflow during temporary file creation leads to an out-of-bounds memory access, allowing an attacker to potentially perform path traversal or access private temporary file content by creating symbolic links. This vulnerability allows a local attacker to manipulate file paths and access unauthorized data. The core issue stems from insufficient validation of file path lengths during temporary file operations.
