Vulnerability Title
Glib: out-of-bounds read in glib/gdatetime.c:g_date_time_get_ymd via invalid gdatetime
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the g_date_time_get_ymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the g_date_time_add_full function is processed. This flaw can corrupt the date output and potentially cause logic errors that may lead to a denial of service.

Vulnerability Title
GNOME glib 缓冲区错误漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
GNOME glib是GNOME基金会开源的一个通用的、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。 GNOME glib 2.86.5之前版本和2.88.1之前版本存在缓冲区错误漏洞，该漏洞源于在glib/gdatetime.c文件的g_date_time_get_ymd函数中存在2字节越界读取，在处理g_date_time_add_full函数生成的无效GDateTime对象时，可破坏日期输出并导致逻辑错误，可能造成拒绝服务。
