high Nessus Plugin ID 167060

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5715-1 advisory.

 - LibRaw before 0.20-RC1 lacks a thumbnail size range check. This affects decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, and utils/thumb_utils.cpp. For example, malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without validating T.tlength. (CVE-2020-15503)

 - In LibRaw, there is an out-of-bounds write vulnerability within the new_node() function (libraw\src\x3f\x3f_utils_patched.cpp) that can be triggered via a crafted X3F file. (CVE-2020-35530)

 - In LibRaw, an out-of-bounds read vulnerability exists within the get_huffman_diff() function (libraw\src\x3f\x3f_utils_patched.cpp) when reading data from an image file. (CVE-2020-35531)

 - In LibRaw, an out-of-bounds read vulnerability exists within the simple_decode_row() function (libraw\src\x3f\x3f_utils_patched.cpp) which can be triggered via an image with a large row_stride field.
 (CVE-2020-35532)

 - In LibRaw, an out-of-bounds read vulnerability exists within the LibRaw::adobe_copy_pixel() function (libraw\src\decoders\dng.cpp) when reading data from the image file. (CVE-2020-35533)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
