The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  • libjpeg-turbo: Stack-based buffer overflow in the transform component (CVE-2020-17541)

  • libjpeg-turbo 1.5.2 has a NULL Pointer Dereference in jdpostct.c and jquant1.c via a crafted JPEG file.
    (CVE-2017-15232)

  • The fill_input_buffer function in jdatasrc.c in libjpeg-turbo 1.5.1 allows remote attackers to cause a denial of service (invalid memory access and application crash) or possibly have unspecified other impact via a crafted jpg file. NOTE: Maintainer asserts the issue is due to a bug in downstream code caused by misuse of the libjpeg API (CVE-2017-9614)

  • In libjpeg-turbo 2.0.2, a large amount of memory can be used during processing of an invalid progressive JPEG image containing incorrect width and height values in the image header. NOTE: the vendor’s expectation, for use cases in which this memory usage would be a denial of service, is that the application should interpret libjpeg warnings as fatal errors (aborting decompression) and/or set limits on resource consumption or image sizes (CVE-2019-13960)

  • libjpeg-turbo version 2.0.90 has a heap-based buffer over-read (2 bytes) in decompress_smooth_data in jdcoefct.c. (CVE-2021-29390)

Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
