samba: Subsequent DCE/RPC fragment injection vulnerability

A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data, bypassing the signature requirements...

kernel: not verifying TKIP MIC of fragmented frames

A vulnerability was found in Linux kernel's WiFi implementation. An attacker within wireless range can inject a control packet fragment where the kernel does not verify the Message Integrity Check authenticity of fragmented TKIP frames...

kernel: reassembling mixed encrypted/plaintext fragments

A flaw was found in ieee80211rxhdefragment in net/mac80211/rx.c in the Linux Kernel's WiFi implementation. This vulnerability can be abused to inject packets or exfiltrate selected fragments when another device sends fragmented frames, and the WEP, CCMP, or GCMP data-confidentiality protocol is...

kernel: reassembling encrypted fragments with non-consecutive packet numbers

A vulnerability was found in Linux kernel, where the WiFi implementation reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP...
