a. vCenter Server Appliance directory traversal The vCenter Server Appliance (vCSA) contains a directory traversal vulnerability that allows an authenticated remote user to retrieve arbitrary files. Exploitation of this issue may expose sensitive information stored on the server. VMware would like to thank Alexander Minozhenko from ERPScan for reporting this issue to us. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-6324 to this issue.

CVE-2009-5029 [MEDIUM] GNU C Library vulnerabilities
Title: GNU C Library vulnerabilities
Summary: Multiple vulnerabilities were discovered and fixed in the GNU C Library.
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. (CVE-2009-5029)
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. (CVE-2010-0015)
Chris Evans reported that the GNU C Library did not properly
calculate the amount of memor

CVE-2009-5029 [MEDIUM] CWE-190 glibc: __tzfile_read integer overflow to buffer overflow
glibc: __tzfile_read integer overflow to buffer overflow
Integer overflow in the __tzfile_read function in glibc before 2.15 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted timezone (TZ) file, as demonstrated using vsftpd.
An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the glibc library read timezone files. If a carefully-crafted timezone file was loaded by an application linked against glibc, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
