   An update that solves four vulnerabilities and has three
   fixes is now available.

Description:

   This update for apache2 fixes the following issues:

   - CVE-2022-23943: heap out-of-bounds write in mod_sed (bsc#1197098).
   - CVE-2022-22720: HTTP request smuggling due to incorrect error handling
     (bsc#1197095).
   - CVE-2022-22719: use of uninitialized value of in r:parsebody in mod_lua
     (bsc#1197091).
   - CVE-2022-22721: possible buffer overflow with very large or unlimited
     LimitXMLRequestBody (bsc#1197096).

   Also TLS 1.3 support and openssl 1.1.1 usage was disabled again as it
   caused regressions in various usage scenarios due to the combination
   between openssl 1.0.2 and 1.1.1 linkage without correct symbol versions by
   other libraries / tools. (bsc#1197301 bsc#1197177 bsc#1196249)
