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

  - A vulnerability, which was classified as problematic, was found in GNU Binutils up to 2.43. This affects
    the function disassemble_bytes of the file binutils/objdump.c. The manipulation of the argument buf leads
    to stack-based buffer overflow. It is possible to initiate the attack remotely. The complexity of an
    attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the
    public and may be used. Upgrading to version 2.44 is able to address this issue. The identifier of the
    patch is baac6c221e9d69335bf41366a1c7d87d8ab2f893. It is recommended to upgrade the affected component.
    (CVE-2025-0840)

  - When the assert() function in the GNU C Library versions 2.13 to 2.40 fails, it does not allocate enough
    space for the assertion failure message string and size information, which may lead to a buffer overflow
    if the message string size aligns to page size. (CVE-2025-0395)

  - Untrusted LD_LIBRARY_PATH environment variable vulnerability in the GNU C Library version 2.27 to 2.38
    allows attacker controlled loading of dynamically shared library in statically compiled setuid binaries
    that call dlopen (including internal dlopen calls after setlocale or calls to NSS functions such as
    getaddrinfo). (CVE-2025-4802)

  - The regcomp function in the GNU C library version from 2.4 to 2.41 is subject to a double free if some
    previous allocation fails. It can be accomplished either by a malloc failure or by using an interposed
    malloc that injects random malloc failures. The double free can allow buffer manipulation depending of how
    the regex is constructed. This issue affects all architectures and ABIs supported by the GNU C library.
    (CVE-2025-8058)

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