The version of LibRaw installed on the remote host is prior to 0.19.4-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2256 advisory.
Buffer Overflow vulnerability in LibRaw::stretch() function in libraw\src\postprocessing\aspect_ratio.cpp.
(CVE-2020-22628)
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)
Buffer Overflow vulnerability in LibRaw linux/unix v0.20.0 allows attacker to escalate privileges via the LibRaw_buffer_datastream::gets(char*, int) in /src/libraw/src/libraw_datastream.cpp. (CVE-2021-32142)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
