The vulnerability of the dynamic loader ld.so, which is responsible for system calls and core functions of glibc, allows a attacker to trigger a memory corruption.

The vulnerability of the dynamic loader ld.so, which provides system calls and core functions of the glibc library, is related to resource management errors. Exploiting this vulnerability allows an attacker to trigger a memory leak by using the environment variable LDHWCAPMASK...

The vulnerability of the getcwd and realpath functions in libraries that provide system calls and the core glibc functions allows a hacker to execute arbitrary code.

The vulnerability of the getcwd and realpath functions in libraries that provide system calls and the main glibc functions arises from operations that go beyond the buffer boundaries in memory. Exploiting this vulnerability allows an attacker to execute arbitrary code using a specially crafted SU...

The vulnerability of the memalign function in libraries that handle system calls and core glibc functions allows a attacker to cause a service failure.

The vulnerability of the memalign function in libraries that handle system calls and core glibc functions arises from a cyclic shift of pointers, which leads to memory overflow. Exploiting this vulnerability can allow an attacker, operating remotely, to cause a service failure...
