Package        : pillow
Version        : 4.0.0-4+deb9u3
CVE ID         : CVE-2020-35653 CVE-2021-25290 CVE-2021-28676 CVE-2021-28677
                 CVE-2021-34552
Debian Bug     : #991293, #989062

Several vulnerabilities have been discovered in pillow (Python Imaging
Library - PIL).

Affected binary packages:

    python-imaging
    python-pil-dbg
    python-pil-doc
    python-pil.imagetk-dbg
    python-pil.imagetk
    python-pil
    python3-pil-dbg
    python3-pil.imagetk-dbg
    python3-pil.imagetk
    python3-pil

CVE-2020-35653

    Pillow through 8.2.0 and PIL (aka Python Imaging Library) through
    1.1.7 allow an attacker to pass controlled parameters directly into
    a convert function to trigger a buffer overflow in Convert.c.

CVE-2021-25290

    An issue was discovered in Pillow before 8.1.1. In TiffDecode.c,
    there is a negative-offset memcpy with an invalid size.

CVE-2021-28676

    An issue was discovered in Pillow before 8.2.0. For FLI data,
    FliDecode did not properly check that the block advance was
    non-zero, potentially leading to an infinite loop on load.

CVE-2021-28677

    An issue was discovered in Pillow before 8.2.0. For EPS data, the
    readline implementation used in EPSImageFile has to deal with any
    combination of \r and \n as line endings. It used an accidentally
    quadratic method of accumulating lines while looking for a line
    ending. A malicious EPS file could use this to perform a DoS of
    Pillow in the open phase, before an image was accepted for opening.

CVE-2021-34552

    Pillow through 8.2.0 and PIL (aka Python Imaging Library) through
    1.1.7 allow an attacker to pass controlled parameters directly into
    a convert function to trigger a buffer overflow in Convert.c.

For Debian 9 stretch, these problems have been fixed in version
4.0.0-4+deb9u3.

We recommend that you upgrade your pillow packages.
