The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3781 advisory.
gdImageClone in gd.c in libgd 2.1.0-rc2 through 2.2.5 has a NULL pointer dereference allowing attackers to crash an application via a specific function call sequence. Only affects PHP when linked with an external libgd (not bundled). (CVE-2018-14553)
read_header_tga in gd_tga.c in the GD Graphics Library (aka LibGD) through 2.3.2 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted TGA file. (CVE-2021-38115)
The GD Graphics Library (aka LibGD) through 2.3.2 has an out-of-bounds read because of the lack of certain gdGetBuf and gdPutBuf return value checks. (CVE-2021-40812)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
