Description Tomas Hoger 2011-03-31 08:41:25 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2009-5064 to the following vulnerability:

** DISPUTED ** ldd in the GNU C Library (aka glibc or libc6) 2.13 and
earlier allows local users to gain privileges via a Trojan horse
executable file linked with a modified loader that omits certain
LD_TRACE_LOADED_OBJECTS checks. NOTE: the GNU C Library vendor states
"This is just nonsense. There are a gazillion other ways to introduce
code if people are downloading arbitrary binaries and install them in
appropriate directories or set LD_LIBRARY_PATH etc."
