UAF Learning--Principle and utilization

0x00 UAF principleAs shown in the code above, the pointer P1 request memory, print its address, valueThen release P1.The pointer p2 applies the same size of memory, prints the address of the P2, P1 the value pointed to by the pointerGCC compiles and runs the following results:P1 is the same as the P2 address, after P1 the pointer is released, P2 requests the same size of memory, the operating system assigns the P1 address to P2, modifies the P2 value,

Graphic tutorial: SELinux policy implementation

mysqld_data_t. If an Apache process is intruded, hackers can gain control of the httpd_t process, read the content of the httpd_sys_content_t file, and write data to the httpd_sys_content_rw_t file. However, hackers still cannot read credit card data (mysqld_data_t), even if the compromised process runs as root. In this case, SELinux can significantly mitigate the security threats caused by intrusion activities. MCS force Metaphor As mentioned above, we have entered two Process types: Dog
