The GNU C Library (glibc) is a widely used library for C and C++ applications. It provides essential functions for memory management, string manipulation, and other basic operations. The vulnerability in glibc allows attackers to access a dangling pointer, which can lead to arbitrary code execution on vulnerable systems.
You're affected if you use glibc versions 2.2 or earlier (specifically, versions 450 through 326). Check with: find / -name "libg.so.*" 2>/dev/null
Note that this vulnerability is not related to similar products like GNU C++ Library or other libraries.
Upgrade to glibc version 2.31 or later.
Maven: Update your dependency in the pom.xml file to org.gnu.glibc:glibc:2.31 or higher.
Immediate mitigations:
- Set the tdelete return value statement to a constant (e.g., _TDELETENONE) as a compiler flag.
