Debian Bug : #819969 #902950 #902176
Several vulnerabilities have been resolved in libjpeg-turbo, Debian's
default JPEG implemenation.
The cjpeg utility in libjpeg allowed remote attackers to cause a
denial of service (NULL pointer dereference and application crash) or
execute arbitrary code via a crafted file.
This issue got fixed by the same patch that fixed CVE-2018-11213 and
libjpeg-turbo has been found vulnerable to a denial of service
vulnerability caused by a divide by zero when processing a crafted
BMP image. The issue has been resolved by a boundary check.
The alloc_sarray function in jmemmgr.c allowed remote attackers to
cause a denial of service (divide-by-zero error) via a crafted file.
The issue has been addressed by checking the image size when reading
a targa file and throwing an error when image width or height is 0.
The get_text_gray_row and get_text_rgb_row functions in rdppm.c both
allowed remote attackers to cause a denial of service (Segmentation
fault) via a crafted file.
By checking the range of integer values in PPM text files and adding
checks to ensure values are within the specified range, both issues
For Debian 8 "Jessie", these problems have been fixed in version
We recommend that you upgrade your libjpeg-turbo packages.
