- Out of bound write in mod_authnz_ldap when using too small Accept-Language values.
Summary
In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all.

If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, \u0027en-US\u0027 is truncated to \u0027en\u0027). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "Out of bound write in mod_authnz_ldap when using too small Accept-Language values." } ] } ] }, "references": { "reference_data": [ { "name": "USN-3627-1", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3627-1/" }, { "name": "103512", "refsource": "BID", "url": "http://www.securityfocus.com/bid/103512" }, { "name": "DSA-4164", "refsource": "DEBIAN", "url": "https://www.debian.org/security/2018/dsa-4164" }, { "name": "https://security.netapp.com/advisory/ntap-20180601-0004/", "refsource": "CONFIRM", "url": "https://security.netapp.com/advisory/ntap-20180601-0004/" }, { "name": "RHSA-2018:3558", "refsource": "REDHAT", "url": "https://access.redhat.com/errata/RHSA-2018:3558" }, { "name": "https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US\u0026docId=emr_na-hpesbux03909en_us", "refsource": "CONFIRM", "url": "https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US\u0026docId=emr_na-hpesbux03909en_us" }, { "name": "RHSA-2019:0367", "refsource": "REDHAT", "url": "https://access.redhat.com/errata/RHSA-2019:0367" }, { "name": "USN-3627-2", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3627-2/" }, { "name": "[oss-security] 20180323 CVE-2017-15710: Out of bound write in mod_authnz_ldap when using too small Accept-Language values", "refsource": "MLIST", "url": "http://www.openwall.com/lists/oss-security/2018/03/24/8" }, { "name": "1040569", "refsource": "SECTRACK", "url": "http://www.securitytracker.com/id/1040569" }, { "name": "https://httpd.apache.org/security/vulnerabilities_24.html", "refsource": "CONFIRM", "url": "https://httpd.apache.org/security/vulnerabilities_24.html" }, { "name": "[debian-lts-announce] 20180530 [SECURITY] [DLA 1389-1] apache2 security update", "refsource": "MLIST", "url": "https://lists.debian.org/debian-lts-announce/2018/05/msg00020.html" }, { "name": "RHSA-2019:0366", "refsource": "REDHAT", "url": "https://access.redhat.com/errata/RHSA-2019:0366" }, { "name": "USN-3937-2", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3937-2/" }, { "name": "[httpd-cvs] 20190815 svn commit: r1048743 [4/4] -
