The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3223 advisory.

  • The DGifDecompressLine function in dgif_lib.c in GIFLIB (possibly version 3.0.x), as later shipped in cgif.c in sam2p 0.49.4, has a heap-based buffer overflow because a certain Private->RunningCode - 2 array index is not checked. This will lead to a denial of service or possibly unspecified other impact.
    (CVE-2018-11490)

  • In GIFLIB before 2019-02-16, a malformed GIF file triggers a divide-by-zero exception in the decoder function DGifSlurp in dgif_lib.c if the height field of the ImageSize data structure is equal to zero.
    (CVE-2019-15133)

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