[PATCH 1/4] python3-cryptography: set CVE_PRODUCT

[PATCH 1/4] python3-cryptography: set CVE_PRODUCT

[mark.yang]

From: "mark.yang" <mark.yang@lge.com>

NVD lists it as cryptography.io:cryptography,
and CNA lists it as pyca:cryptography, so CVE_PRODUCT is set to cryptography.

[PATCH 2/4] python3-ply: set CVE_PRODUCT and CVE_STATUS for CVE-2025-56005 as disputed

[mark.yang]

From: "mark.yang" <mark.yang@lge.com>

For python3-ply, the CVE_PRODUCT should be set to ply, not python:ply.
NVD registers ply as dabeaz:ply, so the default python:ply vendor prefix never matches and no CVEs are reported.

CVE-2025-56005 is disputed.

[PATCH 3/4] python3-pyasn1: set CVE_PRODUCT

[mark.yang]

From: "mark.yang" <mark.yang@lge.com>

Set the product to pyasn1.

The default python:pyasn1 does not match the NVD/CNA entries which use pyasn1 as vendor, so CVEs like CVE-2026-30922
are never reported.

[PATCH 4/4] libx11-compose-data: set CVE_PRODUCT to empty value

[mark.yang]

From: "mark.yang" <mark.yang@lge.com>

This recipe only builds and installs the compose data files (nls/) from
the libX11 sources and contains no compiled libX11 code, so libx11 CVEs
do not apply to it. When the x11 DISTRO_FEATURE is enabled this recipe
is skipped and libx11 itself is built and scanned instead.

Hi,

The NVD entry [1] says:

  A third-party states that this vulnerability should be rejected
  because the proof of concept does not demonstrate arbitrary code
  execution and fails to complete successfully.

Following the links in the NVD entry I see what I assume is the argument
to dispute this [2] and an argument to dispute the dispute [3]. It's not
very convincing to me. I think we need a more clear reason why we want
to ignore this CVE.

[2]: https://github.com/tom025/ply_exploit_rejection
[3]: https://www.openwall.com/lists/oss-security/2026/01/29/1

Best regards,

Where we know the exact CPE that is used, we should use it.  Can you set CVE_PRODUCT to pyasn1:pyasn1 instead.

“cryptography” is vague and will no doubt cause false-positives in the future, and CVE_PRODUCT is actually a list, so setting it to "cryptography.io:cryptography pyca:cryptography” will match correctly and precisely.
