    (CVE-2016-4493)

  - GCC v12.0 was discovered to contain an uncontrolled recursion via the component libiberty/rust-demangle.c.
    This vulnerability allows attackers to cause a Denial of Service (DoS) by consuming excessive CPU and     memory resources. (CVE-2021-46195)

  - **DISPUTED**A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows     an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your     application without this being detected. This stack-protector failure only applies to C99-style     dynamically-sized local variables or those created using alloca(). The stack-protector operates as     intended for statically-sized local variables. The default behavior when the stack-protector detects an     overflow is to terminate your application, resulting in controlled loss of availability. An attacker who     can exploit a buffer overflow without triggering the stack-protector might be able to change program flow     control to cause an uncontrolled loss of availability or to go further and affect confidentiality or     integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by     itself. (CVE-2023-4039)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
