apache2 vulnerabilities
Details

Alex Nichols and Jakob Hirsch discovered that the Apache HTTP Server mod_authnz_ldap module incorrectly handled missing charset encoding headers. A remote attacker could possibly use this issue to cause the server to crash, resulting in a denial of service. (CVE-2017-15710)

Elar Lang discovered that the Apache HTTP Server incorrectly handled certain characters specified in . A remote attacker could possibly use this issue to upload certain files, contrary to expectations. (CVE-2017-15715)

It was discovered that the Apache HTTP Server mod_session module incorrectly handled certain headers. A remote attacker could possibly use this issue to influence session data. (CVE-2018-1283)

Robert Swiecki discovered that the Apache HTTP Server incorrectly handled certain requests. A remote attacker could possibly use this issue to cause the server to crash, leading to a denial of service. (CVE-2018-1301)

Robert Swiecki discovered that the Apache HTTP Server mod_cache_socache module incorrectly handled certain headers. A remote attacker could possibly use this issue to cause the server to crash, leading to a denial of service. (CVE-2018-1303)

Nicolas Daniels discovered that the Apache HTTP Server incorrectly generated the nonce when creating HTTP Digest authentication challenges. A remote attacker could possibly use this issue to replay HTTP requests across a cluster of servers. (CVE-2018-1312)
