EulerOS 2.0 SP8 : httpd (EulerOS-SA-2021-2298)

high Nessus Plugin ID 152332

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the httpd packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow.(CVE-2020-35452)

- Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can cause a NULL pointer dereference and crash, leading to a possible Denial Of Service(CVE-2021-26690)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected httpd packages.
