Amazon Linux AMI : libtiff (ALAS-2020-1447)

high Nessus Plugin ID 142980

Language:

Synopsis

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

Description

The version of libtiff installed on the remote host is prior to 4.0.3-35.36. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1447 advisory.

_TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in LibTIFF through 4.0.10 mishandle Integer Overflow checks because they rely on compiler behavior that is undefined by the applicable C standards. This can, for example, lead to an application crash. (CVE-2019-14973)

tif_getimage.c in LibTIFF through 4.0.10, as used in GDAL through 3.0.1 and other products, has an integer overflow that potentially causes a heap-based buffer overflow via a crafted RGBA image, related to a Negative-size-param condition. (CVE-2019-17546)

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 'yum update libtiff' to update your system.
