EulerOS 2.0 SP5 : fetchmail (EulerOS-SA-2021-2658)

high Nessus Plugin ID 155139

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - report_vbuild in report.c in Fetchmail before 6.4.20 sometimes omits initialization of the vsnprintf va_list argument, which might allow mail servers to cause a denial of service or possibly have unspecified other impact via long error messages. NOTE: it is unclear whether use of Fetchmail on any realistic platform results in an impact beyond an inconvenience to the client user. (CVE-2021-36386)

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 fetchmail packages.
