Package        : libjpeg-turbo
Version        : 1:1.3.1-12+deb8u1

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.
