The remote Fedora 32 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-4e40ccb5e6 advisory.
Incorrect handling of input data in verifyAttribute function in the libmysofa library 0.5 - 1.1 will lead to NULL pointer dereference and segmentation fault error in case of restrictive memory protection or near NULL pointer overwrite in case of no memory restrictions (e.g. in embedded environments). (CVE-2020-36148)
Incorrect handling of input data in changeAttribute function in the libmysofa library 0.5 - 1.1 will lead to NULL pointer dereference and segmentation fault error in case of restrictive memory protection or near NULL pointer overwrite in case of no memory restrictions (e.g. in embedded environments). (CVE-2020-36149)
Incorrect handling of input data in loudness function in the libmysofa library 0.5 - 1.1 will lead to heap buffer overflow and access to unallocated memory block. (CVE-2020-36150)
Incorrect handling of input data in mysofa_resampler_reset_mem function in the libmysofa library 0.5 - 1.1 will lead to heap buffer overflow and overwriting large memory block. (CVE-2020-36151)
Buffer overflow in readDataVar in hdf/dataobject.c in Symonics libmysofa 0.5 - 1.1 allows attackers to execute arbitrary code via a crafted SOFA. (CVE-2020-36152)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
