New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis
The remote VMware ESXi 5.0 host is affected by multiple vulnerabilities.
Description
The remote VMware ESXi 5.0 host is affected by Multiple Vulnerabilities :
- An integer overflow condition exists in the
__tzfile_read() function in the glibc library. An unauthenticated, remote attacker can exploit this, via a crafted timezone (TZ) file, to cause a denial of service or the execution of arbitrary code.
(CVE-2009-5029)
- ldd in the glibc library is affected by a privilege escalation vulnerability due to the omission of certain LD_TRACE_LOADED_OBJECTS checks in a crafted executable file. Note that this vulnerability is disputed by the library vendor. (CVE-2009-5064)
- A remote code execution vulnerability exists in the glibc library due to an integer signedness error in the elf_get_dynamic_info() function when the '--verify' option is used. A remote attacker can exploit this by using a crafted ELF program with a negative value for a certain d_tag structure member in the ELF header.
(CVE-2010-0830)
- A flaw exists in OpenSSL due to a failure to properly prevent modification of the ciphersuite in the session cache when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled. A remote attacker can exploit this to force a downgrade to an unintended cipher by intercepting the network traffic to discover a session identifier.
(CVE-2010-4180)
- A flaw exists in OpenSSL due to a failure to properly validate the public parameters in the J-PAKE protocol when J-PAKE is enabled. A remote attacker can exploit this, by sending crafted values in each round of the protocol, to bypass the need for knowledge of the shared secret. (CVE-2010-4252)
- A out-of-bounds memory error exists in OpenSSL that allows a remote attacker to cause a denial of service or possibly obtain sensitive information by using a malformed ClientHello handshake message. This is also known as the 'OCSP stapling vulnerability'.
(CVE-2011-0014)
- A flaw exists in the addmntent() function in the glibc library due to a failure to report the error status for failed attempts to write to the /etc/mtab file. A local attacker can exploit this to corrupt the file by using writes from a process with a small RLIMIT_FSIZE value.
(CVE-2011-1089)
- A flaw exists in the png_set_text_2() function in the file pngset.c in the libpng library due to a failure to properly allocate memory. An unauthenticated, remote attacker can exploit this, via a crafted text chunk in a PNG image file, to trigger a heap-based buffer overflow, resulting in denial of service or the execution of arbitrary code. (CVE-2011-3048)
- A flaw exists in the DTLS implementation in OpenSSL due to performing a MAC check only if certain padding is valid. A remote attacker can exploit this, via a padding oracle attack, to recover the plaintext. (CVE-2011-4108)
- A double-free error exists in OpenSSL when the X509_V_FLAG_POLICY_CHECK is enabled. A remote attacker can exploit this by triggering a policy check failure, resulting in an unspecified impact. (CVE-2011-4109)
- A flaw exists in OpenSSL in the SSL 3.0 implementation due to improper initialization of data structures used for block cipher padding. A remote attacker can exploit this, by decrypting the padding data sent by an SSL peer, to obtain sensitive information. (CVE-2011-4576)
- A denial of service vulnerability exists in OpenSSL when RFC 3779 support is enabled. A remote attacker can exploit this to cause an assertion failure, by using an X.509 certificate containing certificate extension data associated with IP address blocks or Autonomous System (AS) identifiers. (CVE-2011-4577)
- A denial of service vulnerability exists in the RPC implementation in the glibc library due to a flaw in the svc_run() function. A remote attacker can exploit this, via large number of RPC connections, to exhaust CPU resources. (CVE-2011-4609)
- A denial of service vulnerability exists in the Server Gated Cryptography (SGC) implementation in OpenSSL due to a failure to properly handle handshake restarts. A remote attacker can exploit this, via unspecified vectors, to exhaust CPU resources. (CVE-2011-4619)
- A denial of service vulnerability exists in OpenSSL due to improper support of DTLS applications. A remote attacker can exploit this, via unspecified vectors related to an out-of-bounds read error. Note that this vulnerability exists because of an incorrect fix for CVE-2011-4108. (CVE-2012-0050)
- A security bypass vulnerability exists in the glibc library due to an integer overflow condition in the vfprintf() function in file stdio-common/vfprintf.c. An attacker can exploit this, by using a large number of arguments, to bypass the FORTIFY_SOURCE protection mechanism, allowing format string attacks or writing to arbitrary memory. (CVE-2012-0864)
- A denial of service vulnerability exists in the glibc library in the vfprintf() function in file stdio-common/vfprintf.c due to a failure to properly calculate a buffer length. An attacker can exploit this, via a format string that uses positional parameters and many format specifiers, to bypass the FORTIFY_SOURCE format-string protection mechanism, thus causing stack corruption and a crash. (CVE-2012-3404)
- A denial of service vulnerability exists in the glibc library in the vfprintf() function in file stdio-common/vfprintf.c due to a failure to properly calculate a buffer length. An attacker can exploit this, via a format string with a large number of format specifiers, to bypass the FORTIFY_SOURCE format-string protection mechanism, thus triggering desynchronization within the buffer size handling, resulting in a segmentation fault and crash. (CVE-2012-3405)
- A flaw exists in the glibc library in the vfprintf() function in file stdio-common/vfprintf.c due to a failure to properly restrict the use of the alloca() function when allocating the SPECS array. An attacker can exploit this, via a crafted format string using positional parameters and a large number of format specifiers, to bypass the FORTIFY_SOURCE format-string protection mechanism, thus triggering a denial of service or the possible execution of arbitrary code.
(CVE-2012-3406)
- A flaw exists in the glibc library due to multiple integer overflow conditions in the strtod(), strtof(), strtold(), strtod_l(), and other unspecified related functions. A local attacker can exploit these to trigger a stack-based buffer overflow, resulting in an application crash or the possible execution of arbitrary code. (CVE-2012-3480)
- A privilege escalation vulnerability exists in the Virtual Machine Communication Interface (VMCI) due to a failure by control code to properly restrict memory allocation. A local attacker can exploit this, via unspecified vectors, to gain privileges. (CVE-2013-1406)
- An error exists in the implementation of the Network File Copy (NFC) protocol. A man-in-the-middle attacker can exploit this, by modifying the client-server data stream, to cause a denial of service or the execution of arbitrary code. (CVE-2013-1659)
