Summary
Security Advisory ID : BSA-2018-557
Component : Apache HTTPD
Revision : 2.0: Final
In Apache httpd, 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.
Affected Products
No Brocade Fibre Channel technology products from Broadcom are currently known to be affected by this vulnerability.
