An integer overflow in the mtarnext function in src/microtar.c in rxi microtar 0.1.0 allows a remote attacker to cause a denial of service uncontrolled CPU consumption / infinite loop via a crafted tar archive. mtarnext computes the offset to the next record as rounduph.size, 512 +...

kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count()

A use-after-free flaw was found in the Linux kernel's iSCSI target subsystem. In the iscsitdecconnusagecount function, complete is called while still holding the conn-connusagelock spinlock. The waiting thread such as iscsitcloseconnection may wake up immediately and free the iscsitconn structure...

389-ds-base: 389-ds-base: unbounded LDAP controls count in get_ldapmessage_controls_ext() causes CPU and heap amplification (remote DoS)

A flaw was found in 389-ds-base. The getldapmessagecontrolsext function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls...

kernel: ipv6: use RCU in ip6_output()

A use-after-free flaw was found in ip6finishoutput2 in net/ipv6/ip6output.c in ipv6 access. This flaw could allow an attacker to crash the system at device disconnect. This vulnerability could even lead to a kernel information leak problem...

python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens

A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...
