CVE-2025-4802
MediumSummary
In GNU C Library versions 2.27 to 2.38, an untrusted LD_LIBRARY_PATH environment variable vulnerability allows attacker-controlled loading of dynamically shared libraries in statically compiled setuid binaries that call dlopen (including internal dlopen calls after setlocale or calls to NSS functions).
Risk Assessment
The risk includes privilege escalation by an attacker, as they can inject a malicious library into a process with elevated privileges.
Recommendation
It is recommended to upgrade glibc to a version newer than 2.38 that includes a fix for this vulnerability, and avoid using LD_LIBRARY_PATH in setuid contexts.
