CVSS: 7.5EPSS: 1%CPEs: 1EXPL: 2CVE-2022-24795 – Buffer Overflow and Integer Overflow in yajl-ruby
https://notcve.org/view.php?id=CVE-2022-24795
yajl-ruby is a C binding to the YAJL JSON parsing and generation library. The 1.x branch and the 2.x branch of `yajl` contain an integer overflow which leads to subsequent heap memory corruption when dealing with large (~2GB) inputs. The reallocation logic at `yajl_buf.c#L64` may result in the `need` 32bit integer wrapping to 0 when `need` approaches a value of 0x80000000 (i.e. ~2GB of data), which results in a reallocation of buf->alloc into a small heap chunk. These integers are declared as `size_t` in the 2.x branch of `yajl`, which practically prevents the issue from triggering on 64bit platforms, however this does not preclude this issue triggering on 32bit builds on which `size_t` is a 32bit integer. Subsequent population of this under-allocated heap chunk is based on the original buffer size, leading to heap memory corruption. • https://github.com/brianmario/yajl-ruby/blob/7168bd79b888900aa94523301126f968a93eb3a6/ext/yajl/yajl_buf.c#L64 https://github.com/brianmario/yajl-ruby/commit/7168bd79b888900aa94523301126f968a93eb3a6 https://github.com/brianmario/yajl-ruby/security/advisories/GHSA-jj47-x69x-mxrm https://lists.debian.org/debian-lts-announce/2023/07/msg00013.html https://lists.debian.org/debian-lts-announce/2023/08/msg00003.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KLE3C4CECEJ4EUYI56KXI6OWACWXX7 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2021-41816
CGI.escape_html in Ruby before 2.7.5 and 3.x before 3.0.3 has an integer overflow and resultant buffer overflow via a long string on platforms (such as Windows) where size_t and long have different numbers of bytes. This also affects the CGI gem before 0.3.1 for Ruby. El archivo CGI.escape_html en Ruby versiones anteriores a 2.7.5 y 3.x versiones anteriores a 3.0.3, presenta un desbordamiento de enteros y un desbordamiento de búfer resultante por medio de una cadena larga en plataformas (como Windows) donde size_t y long tienen diferentes números de bytes. Esto también afecta a CGI gem versiones anteriores a 0.3.1 para Ruby A flaw was found in the ruby. This issue occurs due to improper bounds checking by a buffer overrun in CGI.escape_html. • https://hackerone.com/reports/1328463 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IUXQCH6FRKANCVZO2Q7D2SQX33FP3KWN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UTOJGS5IEFDK3UOO7IY4OTTFGHGLSWZF https://security-tracker.debian.org/tracker/CVE-2021-41816 https://security.gentoo.org/glsa/202401-27 https://security.netapp.com/advisory/ntap-20220303-0006 https://www.ruby-lang.org/en/news/2021/11/24/buffer-overrun-in-cgi-escape& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •
