Glib: glib: local denial of service via buffer underflow in content type parsing

A flaw was found in Glib's content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability.

缓冲区下溢

glib 缓冲区错误漏洞

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存在缓冲区错误漏洞，该漏洞源于内容类型解析逻辑中存在缓冲区下溢，可能导致整数环绕和指针下溢，造成本地拒绝服务或应用程序不稳定。
