GNU C Library: Multiple Vulnerabilities

Background The GNU C library is the standard C library used by Gentoo Linux systems. It provides programs with basic facilities and interfaces to system calls. ld.so is the dynamic linker which prepares dynamically linked programs for execution by resolving runtime dependencies and related...

fapolicyd: fapolicyd wrongly prepares ld.so path

A vulnerability was found in fapolicyd. The vulnerability occurs due to an assumption on how glibc names the runtime linker, a build time regular expression may not correctly detect the runtime linker. The consequence is that the pattern detection for applications launched by the run time linker...

Linux: Disable prelink

prelink is a program that modifies ELF shared libraries and ELF dynamically linked binaries in such a way that the time needed for the dynamic linker to perform relocations at startup significantly decreases. Copyright C 2020 Greenbone Networks GmbH Some text descriptions might be excerpted from ...

Denial Of Service (DoS)

glibc is vulnerable to privilege escalation. It was discovered that the glibc dynamic linker/loader did not handle the $ORIGIN dynamic string token set in the LDAUDIT environment variable securely. A local attacker with write access to a file system containing setuid or setgid binaries could use...

Privilege Escalation

glibc is vulnerable to privilege escalation. The vulnerability exists as it was discovered that the glibc dynamic linker/loader did not perform sufficient safety checks when loading dynamic shared objects DSOs to provide callbacks for its auditing API during the execution of privileged programs. ...

Recommendations: For Nextcloud Desktop Client version 2.6.2, ...

CVE-2019-19726

OpenBSD through 6.6 allows local users to escalate to root because a check for LDLIBRARYPATH in setuid programs can be defeated by setting a very small RLIMITDATA resource limit. When executing chpass or passwd which are setuid root, dlsetupenv in ld.so tries to strip LDLIBRARYPATH from the...
