Mitigation Bypass in GNU Libc Affects Multiple Platforms
CVE-2019-1010025
5.3MEDIUM
What is CVE-2019-1010025?
The GNU Libc library is vulnerable to a mitigation bypass that allows an attacker to exploit predictable heap addresses of pthread-created threads. While the vendor argues that ASLR bypass itself is not a vulnerability, this weakness can be leveraged by attackers to gain further insight into the memory layout of affected systems, ultimately leading to potential exploitation. Organizations using this library should be aware of the implications and assess their systems accordingly.
