Medium Nessus Plugin ID 129242

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

- The idna_to_ascii_4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via 64 bytes of input.(CVE-2016-6261)

- The stringprep_utf8_nfkc_normalize function in lib/nfkc.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted UTF-8 data.(CVE-2016-6263)

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 libidn packages.
