Amazon Linux 2 Security Advisory: ALAS-2020-1532
Advisory Release Date: 2020-10-22 18:24 Pacific
Advisory Updated Date: 2020-10-22 22:35 Pacific
Severity: Medium

Issue Overview:

_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)
