CVE-2005-4532

scponlyc in scponly 4.1 and earlier, when the operating system supports LDPRELOAD mechanisms, allows local users to execute arbitrary code with root privileges by creating a chroot directory in their home directory, hard linking to a system setuid application, and using a modified LDPRELOAD to...

CVE-2005-4532

CVE-2005-4532 affects scponly versions 4.1 and earlier. The root cause is a design/implementation flaw in scponlyc that can be exploited when LD_PRELOAD is available: an unprivileged user can create a chroot directory in their home, hard-link to a system setuid application, and override expected ...

CVE-2005-3346

Buffer overflow in the environment variable substitution code in main.c in OSH 1.7-14 allows local users to inject arbitrary environment variables, such as LDPRELOAD, via pathname arguments of the form "$VAR/EVAR=arg", which cause the EVAR portion to be appended to a buffer returned by a getenv...

CVE-2005-3346

CVE-2005-3346 affects osh (OSHevironment) 1.7-14, where a buffer overflow in the environment variable substitution code (main.c) can be triggered by pathname args like "$VAR/EVAR=arg". This allows a local attacker to inject arbitrary environment variables (e.g., LD_PRELOAD) and, per Debian's advi...

Debian DSA-039-1 : glibc

The version of GNU libc that was distributed with Debian GNU/Linux 2.2 suffered from 2 security problems : - It was possible to use LDPRELOAD to load libraries that are listed in /etc/ld.so.cache, even for suid programs. This could be used to create and overwrite files which a user should not be...

CVE-2002-1472

CVE-2002-1472 describes an untrusted search path vulnerability in XFree86’s libX11.so used by setuid/setgid programs. A local attacker can leverage a modified LD_PRELOAD to point to a malicious module and gain root privileges; impact is local privilege escalation. The vulnerability is associated ...
