CVE-2026-58216 Samba: kpasswd service: kpasswd packet that contains malformed asn.1 might cause the server to access 6 bytes of unallocated memory leading server to crash
An out-of-bounds read flaw was found in Samba's Kerberos Key Distribution Center's KDC password change kpasswd service. When processing malformed ASN.1-encoded Kerberos password change request, Samba server miscalculates the structure size and attempts to read up to six bytes beyond the end of th...

Name of the Vulnerable Software and Affected Versions pyasn1 versions prior to 0.6.4 Description The univ.Real type converts its mantissa, base, and exponent value to a Python float using exact big-integer exponentiation. A BER, CER, or DER encoded REAL value containing a very large exponent can...
CVE-2026-61447
PraisonAI before 1.6.78 contains a remote code execution vulnerability in CodeAgent.executepython that executes LLM-generated Python code without AST validation, import restrictions, or sandbox enforcement. Attackers can influence LLM output through prompt injection to exfiltrate all environment...
pyasn1: pyasn1: Denial of Service via crafted ASN.1 REAL values
A remote attacker can exploit this by providing specially crafted BER/CER/DER-encoded ASN.1 data with a large exponent in the REAL value. When the application subsequently prints, logs, compares, or performs arithmetic on the decoded value, this can cause excessive CPU and memory consumption,...
