CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 1CVE-2022-39224 – Arbitrary shell execution when extracting or listing files contained in a malicious rpm.
https://notcve.org/view.php?id=CVE-2022-39224
Arr-pm is an RPM reader/writer library written in Ruby. Versions prior to 0.0.12 are subject to OS command injection resulting in shell execution if the RPM contains a malicious "payload compressor" field. This vulnerability impacts the `extract` and `files` methods of the `RPM::File` class of this library. Version 0.0.12 patches these issues. A workaround for this issue is to ensure any RPMs being processed contain valid/known payload compressor values such as gzip, bzip2, xz, zstd, and lzma. • https://github.com/jordansissel/ruby-arr-pm/pull/14 https://github.com/jordansissel/ruby-arr-pm/pull/15 https://github.com/jordansissel/ruby-arr-pm/security/advisories/GHSA-88cv-mj24-8w3q • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

There is a buffer over-read in Ruby before 2.6.10, 2.7.x before 2.7.6, 3.x before 3.0.4, and 3.1.x before 3.1.2. It occurs in String-to-Float conversion, including Kernel#Float and String#to_f. Se presenta una lectura excesiva del búfer en Ruby versiones anteriores a 2.6.10, 2.7.x versiones anteriores a 2.7.6, 3.x versiones anteriores a 3.0.4 y 3.1.x versiones anteriores a 3.1.2. Es producida en la conversión String-to-Float, incluyendo Kernel#Float y String#to_f A buffer overrun vulnerability was found in Ruby. The issue occurs in a conversion algorithm from a String to a Float that causes process termination due to a segmentation fault, but under limited circumstances. • http://seclists.org/fulldisclosure/2022/Oct/28 http://seclists.org/fulldisclosure/2022/Oct/29 http://seclists.org/fulldisclosure/2022/Oct/30 http://seclists.org/fulldisclosure/2022/Oct/41 http://seclists.org/fulldisclosure/2022/Oct/42 https://hackerone.com/reports/1248108 https://lists.debian.org/debian-lts-announce/2023/06/msg00012.html https://security-tracker.debian.org/tracker/CVE-2022-28739 https://security.gentoo.org/glsa/202401-27 https://security.netapp.com/advisory/n • CWE-125: Out-of-bounds Read •

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 •
