Summary

MIT Kerberos 5 (aka krb5) 1.3.x, 1.4.x, 1.5.x, 1.6.x, 1.7.x, and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to modify user-visible prompt text, modify a response to a Key Distribution Center (KDC), or forge a KRB-SAFE message via certain checksums that (1) are unkeyed or (2) use RC4 keys.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Signature Spoofing by Key Recreation
    An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

    descriptionThe MIT Kerberos team reports : MIT krb5 clients incorrectly accept an unkeyed checksums in the SAM-2 preauthentication challenge. An unauthenticated remote attacker could alter a SAM-2 challenge, affecting the prompt text seen by the user or the kind of response sent to the KDC. Under some circumstances, this can negate the incremental security benefit of using a single-use authentication mechanism token. MIT krb5 incorrectly accepts RFC 3961 key-derivation checksums using RC4 keys when verifying KRB-SAFE messages. An unauthenticated remote attacker has a 1/256 chance of forging KRB-SAFE messages in an application protocol if the targeted pre-existing session uses an RC4 session key. Few application protocols use KRB-SAFE messages.

    descriptionUpdated krb5 packages that fix multiple security issues and one bug are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third party, the Key Distribution Center (KDC). Multiple checksum validation flaws were discovered in the MIT Kerberos implementation. A remote attacker could use these flaws to tamper with certain Kerberos protocol packets and, possibly, bypass authentication or authorization mechanisms and escalate their privileges. (CVE-2010-1323, CVE-2010-1324, CVE-2010-4020) Red Hat would like to thank the MIT Kerberos Team for reporting these issues. This update also fixes the following bug : * When attempting to perform PKINIT pre-authentication, if the client had more than one possible candidate certificate the client could fail to select the certificate and key to use. This usually occurred if certificate selection was configured to use the value of the keyUsage extension, or if any of the candidate certificates did not contain a subjectAltName extension. Consequently, the client attempted to perform pre-authentication using a different (usually password-based) mechanism. (BZ#644825) All krb5 users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically.

    descriptionUpdated krb5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third party, the Key Distribution Center (KDC). Multiple checksum validation flaws were discovered in the MIT Kerberos implementation. A remote attacker could use these flaws to tamper with certain Kerberos protocol packets and, possibly, bypass authentication mechanisms in certain configurations using Single-use Authentication Mechanisms. (CVE-2010-1323) Red Hat would like to thank the MIT Kerberos Team for reporting these issues. All krb5 users should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically.

Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third party, the Key Distribution Center (KDC).

    descriptionThe remote VMware ESX / ESXi host is missing a security-related patch. It is, therefore, affected by multiple vulnerabilities : - Multiple forgery vulnerabilities exist in the bundled version of MIT Kerberos 5 (krb5). An attacker can exploit these issues to impersonate a client, escalate privileges, and disclose sensitive information. (CVE-2010-1323, CVE-2010-1324, CVE-2010-4020, CVE-2010-4021) - A local arbitrary code execution vulnerability exists in the Kernel in the do_anonymous_page() function due to improper separation of the stack and the heap. A local attacker can exploit this vulnerability to execute arbitrary code. (CVE-2010-2240) - A denial of service vulnerability exists that allows a remote attacker to exhaust available sockets, preventing further connections. (CVE-2011-1785) - A denial of service vulnerability exists in the bundled version of lsassd in Likewise Open. A remote attacker can exploit this, via an Active Directory login attempt that provides a username containing an invalid byte sequence, to cause a daemon crash. (CVE-2011-1786)

    titleVMware ESX / ESXi Multiple Vulnerabilities (VMSA-2011-0007) (remote check)
  • NASL familyVMware ESX Local Security Checks
    NASL idVMWARE_VMSA-2011-0007.NASL
    descriptiona. ESX/ESXi Socket Exhaustion By sending malicious network traffic to an ESXi or ESX host an attacker could exhaust the available sockets which would prevent further connections to the host. In the event a host becomes inaccessible its virtual machines will continue to run and have network connectivity but a reboot of the ESXi or ESX host may be required in order to be able to connect to the host again. ESXi and ESX hosts may intermittently lose connectivity caused by applications that do not correctly close sockets. If this occurs an error message similar to the following may be written to the vpxa log : socket() returns -1 (Cannot allocate memory) An error message similar to the following may be written to the vmkernel logs : socreate(type=2, proto=17) failed with error 55 VMware would like to thank Jimmy Scott at inet-solutions.be for reporting this issue to us. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2011-1785 to this issue. b. Likewise package update Updates to the vmware-esx-likewise-openldap and vmware-esx-likewise-krb5 packages address several security issues. One of the vulnerabilities is specific to Likewise while the other vulnerabilities are present in the MIT version of krb5. An incorrect assert() call in Likewise may lead to a termination of the Likewise-open lsassd service if a username with an illegal byte sequence is entered for user authentication when logging in to the Active Directory domain of the ESXi/ESX host. This would lead to a denial of service. The MIT-krb5 vulnerabilities are detailed in MITKRB5-SA-2010-007. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2011-1786 (Likewise-only issue), CVE-2010-1324, CVE-2010-1323, CVE-2010-4020, CVE-2010-4021 to these issues. c. ESX third-party update for Service Console kernel The Service Console kernel is updated to include a fix for a security issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-2240 to this issue.

    descriptionMultiple vulnerabilities were discovered and corrected in krb5 : An unauthenticated remote attacker could alter a SAM-2 challenge, affecting the prompt text seen by the user or the kind of response sent to the KDC. Under some circumstances, this can negate the incremental security benefit of using a single-use authentication mechanism token. An unauthenticated remote attacker has a 1/256 chance of forging KRB-SAFE messages in an application protocol if the targeted pre-existing session uses an RC4 session key. Few application protocols use KRB-SAFE messages (CVE-2010-1323). An unauthenticated remote attacker can forge GSS tokens that are intended to be integrity-protected but unencrypted, if the targeted pre-existing application session uses a DES session key. An authenticated remote attacker can forge PACs if using a KDC that does not filter client-provided PAC data. This can result in privilege escalation against a service that relies on PAC contents to make authorization decisions. An unauthenticated remote attacker has a 1/256 chance of swapping a client-issued KrbFastReq into a different KDC-REQ, if the armor key is RC4. The consequences are believed to be minor (CVE-2010-1324). An authenticated remote attacker that controls a legitimate service principal has a 1/256 chance of forging the AD-SIGNEDPATH signature if the TGT key is RC4, allowing it to use self-generated evidence tickets for S4U2Proxy, instead of tickets obtained from the user or with S4U2Self. Configurations using RC4 for the TGT key are believed to be rare. An authenticated remote attacker has a 1/256 chance of forging AD-KDC-ISSUED signatures on authdata elements in tickets having an RC4 service key, resulting in privilege escalation against a service that relies on these signatures. There are no known uses of the KDC-ISSUED authdata container at this time (CVE-2010-4020. An authenticated remote attacker that controls a legitimate service principal could obtain a valid service ticket to itself containing valid KDC-generated authorization data for a client whose TGS-REQ it has intercepted. The attacker could then use this ticket for S4U2Proxy to impersonate the targeted client even if the client never authenticated to the subverted service. The vulnerable configuration is believed to be rare (CVE-2010-4021). The updated packages have been patched to correct this issue.

descriptionMIT Kerberos 5 (aka krb5) 1.3.x, 1.4.x, 1.5.x, 1.6.x, 1.7.x, and 1.8.x through 1.8.3 does not properly determine the acceptability of checksums, which might allow remote attackers to modify user-visible prompt text, modify a response to a Key Distribution Center (KDC), or forge a KRB-SAFE message via certain checksums that (1) are unkeyed or (2) use RC4 keys.
