Description

Exim before 4.99.3, in certain GnuTLS configurations, has a remotely reachable use-after-free in the BDAT body parsing path. It is triggered when a client sends a TLS close_notify mid-body during a CHUNKING transfer, followed by a final cleartext byte on the same TCP connection. This can lead to heap corruption. An unauthenticated network attacker exploiting this vulnerability could execute arbitrary code.

I didn't think I would ever use this sentence, but "thank fuck I use openssl"…

Then again it'll be the other way around some future time. Near future probably, considering how things are going.

(My primary server is still running Gentoo, so, exim is indeed built against openssl. Unlike all my Debian boxes…)

As I was saying, we're not done with page cache LPEs.

Looks like a third variant just dropped (CVE-2026-46300):

Initial reading is defense against #DirtyFrag mitigates this, too, so perhaps not a full round of updates needed here.

Microsoft Patch Tuesday 05/2026:
- opravy 120 zranitelností ve Windows, Officech, ale také třeba Malování(!)
- 17 kritických (z toho 14x RCE)
- krom toho mnoho (130+) oprav Edge nebo Teamsů

Velmi zajímavě vypadá zranitelnost CVE-2026-41096 ve Windows DNS klientovi(!), která umožňuje vzdálené spuštění kódu podstrčením připravených DNS odpovědí. S tím bych se vyloženě bál připojit se k sítím s cizím DNS.

Description

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Also unshare DATA/RESPONSE packets when paged frags are present The DATA-packet handler in rxrpc_input_call_event() and the RESPONSE handler in rxrpc_verify_response() copy the skb to a linear one before calling into the security ops only when skb_cloned() is true. An skb that is not cloned but still carries externally-owned paged fragments (e.g. SKBFL_SHARED_FRAG set by splice() into a UDP socket via __ip_append_data, or a chained skb_has_frag_list()) falls through to the in-place decryption path, which binds the frag pages directly into the AEAD/skcipher SGL via skb_to_sgvec(). Extend the gate to also unshare when skb_has_frag_list() or skb_has_shared_frag() is true. This catches the splice-loopback vector and other externally-shared frag sources while preserving the zero-copy fast path for skbs whose frags are kernel-private (e.g. NIC page_pool RX, GRO). The OOM/trace handling already in place is reused.

Description

Ollama before 0.17.1 contains a heap out-of-bounds read vulnerability in the GGUF model loader. The /api/create endpoint accepts an attacker-supplied GGUF file in which the declared tensor offset and size exceed the file's actual length; during quantization in fs/ggml/gguf.go and server/quantization.go (WriteTo()), the server reads past the allocated heap buffer. The leaked memory contents may include environment variables, API keys, system prompts, and concurrent users' conversation data, and can be exfiltrated by uploading the resulting model artifact through the /api/push endpoint to an attacker-controlled registry. The /api/create and /api/push endpoints have no authentication in the upstream distribution. Default deployments bind to 127.0.0.1, but the documented OLLAMA_HOST=0.0.0.0 configuration is widely used in practice (large public-internet exposure observed).
