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

  - 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)

  - 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)

  - 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 8.2.0. 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)

  - 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)

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.

远程 Debian 9 主机上安装的多个程序包受到 dla-2716 公告中提及的多个漏洞影响。

  - 在 8.1.0 之前的 Pillow 中，PcxDecode 在解码构建的 PCX 文件时出现缓冲区过度读取，这是因为缓冲区计算信任用户提供的步幅值。(CVE-2020-35653)

  - 在 Pillow 8.1.1 之前的版本中发现问题。TiffDecode.c 中存在具有无效大小的负偏移 memcpy。(CVE-2021-25290)

  - 在 Pillow 8.2.0 之前的版本中发现问题。对于 FLI 数据，FliDecode 未正确检查区块推进是否非零，这可能导致加载操作无限循环。(CVE-2021-28676)

  - 在 Pillow 8.2.0 之前的版本中发现问题。对于 EPS 数据，EPSImageFile 中使用的 readline 实现必须将 \r 和 \n 的任意组合作为行末进行处理。它在查找行末时意外使用了累积行的二次方法。恶意 EPS 文件可利用此漏洞，在接受要打开的图像之前，在打开阶段执行 DoS of Pillow。
    (CVE-2021-28677)

  - Pillow 至 8.2.0 和 PIL（即 Python Imaging Library）至 1.1.7 允许攻击者直接将受控参数传递至 convert 函数，以触发 Convert.c 中的缓冲区溢出。
