CVE-2011-1658

Status Candidate

Overview

ld.so in the GNU C Library (aka glibc or libc6) 2.13 and earlier expands the $ORIGIN dynamic string token when RPATH is composed entirely of this token, which might allow local users to gain privileges by creating a hard link in an arbitrary directory to a (1) setuid or (2) setgid program with this RPATH value, and then executing the program with a crafted value for the LD_PRELOAD environment variable, a different vulnerability than CVE-2010-3847 and CVE-2011-0536. NOTE: it is not expected that any standard operating-system distribution would ship an applicable setuid or setgid program.

Ubuntu Security Notice USN-1396-1

Ubuntu Security Notice 1396-1 - It was discovered that the GNU C Library did not properly handle integer overflows in the timezone handling code. An attacker could use this to possibly execute arbitrary code by convincing an application to load a maliciously constructed tzfile. It was discovered that the GNU C Library did not properly handle passwd.adjunct.byname map entries in the Network Information Service (NIS) code in the name service caching daemon (nscd). An attacker could use this to obtain the encrypted passwords of NIS accounts. This issue only affected Ubuntu 8.04 LTS. Various other issues were also addressed.
