CVE-2026-63550
The CVE-2026-63550 issue affects the MMS BER decoder, where a boundary-handling flaw in processing certain fields of confirmed-request messages can cause the decoder to advance its read position incorrectly on receiving a BER-encoded element over an established MMS session (TCP port 102). This ma...
CVE-2026-66349
The CVE-2026-66349 entry concerns the MMS server connection handler. A flaw in processing BER-encoded request data occurs when an MMS confirmed request PDU with an extended BER tag is received over an established session, where a missing bounds check can cause the decoder to advance its internal ...
PYSEC-2026-3457
pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the univ.Real type converted its mantissa, base, and exponent value to a Python float using exact big-integer exponentiation. A BER, CER, or DER encoded REAL value only a few bytes long can carry a very large exponent, causing float...
