Mageia 6: MGASA-2018-0460 Moderate: Apache Denial Of Service

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 (CVE-2017-15710).
A regular expression could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. leading to corruption of uploaded files (CVE-2017-15715).
