Amazon Linux 2022 : httpd, httpd-core, httpd-devel (ALAS2022-2022-053)

critical Nessus Plugin ID 164751

Language:

Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-053 advisory.

 A flaw was found in the mod_lua module of httpd. A crafted request body can cause a read to a random memory area due to an uninitialized value in functions called by the parsebody function. The highest treat of this vulnerability is availability. (CVE-2022-22719)

 A flaw was found in httpd. The inbound connection is not closed when it fails to discard the request body, which may expose the server to HTTP request smuggling. (CVE-2022-22720)

 A flaw was found in httpd, where it incorrectly limits the value of the LimitXMLRequestBody option. This issue can lead to an integer overflow and later causes an out-of-bounds write. (CVE-2022-22721)

 An out-of-bounds read/write vulnerability was found in the mod_sed module of httpd. This flaw allows an attacker to overwrite the memory of an httpd instance that is using mod_sed with data provided by the attacker. (CVE-2022-23943)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update --releasever=2022.0.20220419 httpd' to update your system.
