"The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple
vulnerabilities as referenced in the 304d92c3-00c5-11ef-bd52-080027bff743 advisory.

  - stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may
    trigger out of bounds write in `f->vendor[i] = get8_packet(f);`. The root cause is an integer overflow in
    `setup_malloc`. A sufficiently large value in the variable `sz` overflows with `sz+7` in and the negative
    value passes the maximum available memory buffer check. This issue may lead to code execution.
    (CVE-2023-45676)

  - stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may
    trigger out of bounds write in `f->vendor[len] = (char)'\0';`. The root cause is that if `len` read in
    `start_decoder` is a negative number and `setup_malloc` successfully allocates memory in that case, but
    memory write is done with a negative index `len`. Similarly if len is INT_MAX the integer overflow len+1
    happens in `f->vendor = (char*)setup_malloc(f, sizeof(char) * (len+1));` and `f->comment_list[i] =
    (char*)setup_malloc(f, sizeof(char) * (len+1));`. This issue may lead to code execution. (CVE-2023-45677)

  - stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may
    trigger memory allocation failure in `start_decoder`. In that case the function returns early, the
    `f->comment_list` is set to `NULL`, but `f->comment_list_length` is not reset. Later in `vorbis_deinit` it
    tries to dereference the `NULL` pointer. This issue may lead to denial of service. (CVE-2023-45680)

  - stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may
    trigger memory write past an allocated heap buffer in `start_decoder`. The root cause is a potential
    integer overflow in `sizeof(char*) * (f->comment_list_length)` which may make `setup_malloc` allocate less
    memory than required. Since there is another integer overflow an attacker may overflow it too to force
    `setup_malloc` to return 0 and make the exploit more reliable. This issue may lead to code execution.
    (CVE-2023-45681)

  - stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may
    trigger out of bounds read in `DECODE` macro when `var` is negative. As it can be seen in the definition
    of `DECODE_RAW` a negative `var` is a valid value. This issue may be used to leak internal memory
    allocation information. (CVE-2023-45682)

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