"The remote NewStart CGSL host, running version MAIN 7.02, has libvirt packages installed that are affected by multiple
vulnerabilities:

  - A race condition leading to a stack use-after-free flaw was found in libvirt. Due to a bad assumption in
    the virNetClientIOEventLoop() method, the `data` pointer to a stack-allocated virNetClientIOEventData
    structure ended up being used in the virNetClientIOEventFD callback while the data pointer's stack frame
    was concurrently being freed when returning from virNetClientIOEventLoop(). The 'virtproxyd' daemon can
    be used to trigger requests. If libvirt is configured with fine-grained access control, this issue, in
    theory, allows a user to escape their otherwise limited access. This flaw allows a local, unprivileged
    user to access virtproxyd without authenticating. Remote users would need to authenticate before they
    could access it. (CVE-2024-4418)

  - An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number
    of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially
    crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack
    by causing the libvirt daemon to crash. (CVE-2024-1441)

  - A flaw was found in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory
    for arrays before the non-negative length check is performed by the C API entry points. Passing a negative
    length to the g_new0 function results in a crash due to the negative length being treated as a huge
    positive number. This flaw allows a local, unprivileged user to perform a denial of service attack by
    causing the libvirt daemon to crash. (CVE-2024-2494)

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