Package        : pyasn1
CVE ID         : CVE-2026-30922
Debian Bug     : 1131371

It was discovered that pyasn1, a generic ASN.1 library for Python, is
prone to a denial of service vulnerability when decoding ASN.1 data with
deeply nested structures.

For the oldstable distribution (bookworm), this problem has been fixed
in version 0.4.8-3+deb12u2.

For the stable distribution (trixie), this problem has been fixed in
version 0.6.1-1+deb13u2.

We recommend that you upgrade your pyasn1 packages.

For the detailed security status of pyasn1 please refer to its security
tracker page at:
