Subject: [PATCH] Plug memory leak that happens upon error.
|
||
|
|
||
|
If fgStructure.CurrentMenu is set when glutAddMenuEntry() or
|
||
|
glutAddSubMenu() is called the allocated menuEntry variable will
|
||
|
leak. This commit postpones allocating menuEntry until after the
|
||
|
error checks, thereby plugging the memory leak.
|
||
|
|
||
|
This fixes CVE-2024-24258 and CVE-2024-24259.
