The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-ff6a72d8e9 advisory.
A heap-based buffer overflow vulnerability exists in the .egi parsing functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .egi file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2024-21795)
An integer overflow vulnerability exists in the sopen_FAMOS_read functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .famos file can lead to an out-of-bounds write which in turn can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2024-21812)
A double-free vulnerability exists in the BrainVision Header Parsing functionality of The Biosig Project libbiosig Master Branch (ab0ee111) and 2.5.0. A specially crafted .vdhr file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2024-22097)
An out-of-bounds write vulnerability exists in the BrainVisionMarker Parsing functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .vmrk file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2024-23305)
A use-after-free vulnerability exists in the sopen_FAMOS_read functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .famos file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2024-23310)
An integer underflow vulnerability exists in the sopen_FAMOS_read functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .famos file can lead to an out-of-bounds write which in turn can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2024-23313)
An out-of-bounds write vulnerability exists in the sopen_FAMOS_read functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .famos file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2024-23606)
A double-free vulnerability exists in the BrainVision ASCII Header Parsing functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .vdhr file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2024-23809)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
