Azure Linux 3.0 Security Update: dietlibc (CVE-2015-1473)

high Nessus Plugin ID 295511

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of dietlibc installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2015-1473 advisory.

 - The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service (segmentation violation) or overwrite memory locations beyond the stack boundary via a long line containing wide characters that are improperly handled in a wscanf call. (CVE-2015-1473)

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

Solution

Update the affected packages.
