[debian-lts-announce] 20210722 [SECURITY] [DLA 2716-1] pillow security update

According to the versions of the python-pillow package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - An issue was discovered in Pillow before 8.2.0.
    PSDImagePlugin.PsdImageFile lacked a sanity check on     the number of input layers relative to the size of the     data block. This could lead to a DoS on Image.open     prior to Image.load.(CVE-2021-28675)

  - 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-2021-28676)

  - 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-2021-28677)

  - An issue was discovered in Pillow before 8.1.1. In     TiffDecode.c, there is a negative-offset memcpy with an     invalid size.(CVE-2021-25290)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the python-pillow packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - An issue was discovered in Pillow before 8.2.0. There     is an out-of-bounds read in J2kDecode, in     j2ku_graya_la.(CVE-2021-25287)

  - An issue was discovered in Pillow before 8.2.0. There     is an out-of-bounds read in J2kDecode, in     j2ku_gray_i.(CVE-2021-25288)

  - Pillow before 8.1.1 allows attackers to cause a denial     of service (memory consumption) because the reported     size of a contained image is not properly checked for a     BLP container, and thus an attempted memory allocation     can be very large.(CVE-2021-27921)

  - Pillow before 8.1.1 allows attackers to cause a denial     of service (memory consumption) because the reported     size of a contained image is not properly checked for     an ICNS container, and thus an attempted memory     allocation can be very large.(CVE-2021-27922)

  - Pillow before 8.1.1 allows attackers to cause a denial     of service (memory consumption) because the reported     size of a contained image is not properly checked for     an ICO container, and thus an attempted memory     allocation can be very large.(CVE-2021-27923)

  - An issue was discovered in Pillow before 8.2.0.
    PSDImagePlugin.PsdImageFile lacked a sanity check on     the number of input layers relative to the size of the     data block. This could lead to a DoS on Image.open     prior to Image.load.(CVE-2021-28675)

  - An issue was discovered in Pillow before 8.2.0. For BLP     data, BlpImagePlugin did not properly check that reads     (after jumping to file offsets) returned data. This     could lead to a DoS where the decoder could be run a     large number of times on empty data.(CVE-2021-28678)

  - In Pillow before 8.1.0, SGIRleDecode has a 4-byte     buffer over-read when decoding crafted SGI RLE image     files because offsets and length tables are     mishandled.(CVE-2020-35655)

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2716 advisory.

  - In Pillow before 8.1.0, PcxDecode has a buffer over-read when decoding a crafted PCX file because the     user-supplied stride value is trusted for buffer calculations. (CVE-2020-35653)

  - An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is a negative-offset memcpy with an     invalid size. (CVE-2021-25290)

  - 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-2021-28676)

  - 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-2021-28677)

  - 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-2021-34552)
