GHSA-mvp5-qx9c-c3fv: XWiki makes title of inaccessible pages available through the class property values REST API
ImpactThe title of every single page whose reference is known can be accessed through the REST API as long as an XClass with a page property is accessible, this is the default for an XWiki installation. This allows an attacker to get titles of pages whose reference is known, one title per request. This doesn't affect fully [private wikis](https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Access%20Rights/#HPrivateWiki) as the REST endpoint checks access rights on the XClass definition. The impact on confidentiality depends on the strategy for page names. By default, page names match the title, so the impact should be low but if page names are intentionally obfuscated because the titles are sensitive, the impact could be high.PatchesThis has been fixed in XWiki 16.4.7, 16.10.3 and 17.0.0 by adding access control checks before getting the title of any page.WorkaroundsWe're not aware of any workarounds.

GHSA-pp4v-xc4h-7x6m: In the Linux kernel, the following vulnerability has been resolved:crypto: acomp - fix wrong pointer stored by acomp_save_req()acomp_save_req() stores &req->chain in req->base.data. When
acomp_reqchain_done() is invoked on asynchronous completion, it receives
&req->chain as the data argument but casts it directly to struct
acomp_req. Since data points to the chain member, all subsequent field
accesses are at a wrong offset, resulting in memory corruption.The issue occurs when an asynchronous hardware implementation, such as
the QAT driver, completes a request that uses the DMA virtual address
interface (e.g. acomp_request_set_src_dma()). This combination causes
crypto_acomp_compress() to enter the acomp_do_req_chain() path, which
sets acomp_reqchain_done() as the completion callback via
acomp_save_req().With KASAN enabled, this manifests as a general protection fault in
acomp_reqchain_done():general protection fault, probably for non-canonical address 0xe000040000000000
  KASAN: probably user-memory-access in range [0x0000400000000000-0x0000400000000007]

CVE-2020-26262: Loopback bypass in Coturn
Coturn is free open source implementation of TURN and STUN Server. Coturn before version 4.5.2 by default does not allow peers to connect and relay packets to loopback addresses in the range of `127.x.x.x`. However, it was observed that when sending a `CONNECT` request with the `XOR-PEER-ADDRESS` value of `0.0.0.0`, a successful response was received and subsequently, `CONNECTIONBIND` also received a successful response. Coturn then is able to relay packets to the loopback interface. Additionally, when coturn is listening on IPv6, which is default, the loopback interface can also be reached by making use of either `[::1]` or `[::]` as the peer address. By using the address `0.0.0.0` as the peer address, a malicious user will be able to relay packets to the loopback interface, unless `--denied-peer-ip=0.0.0.0` (or similar) has been specified. Since the default configuration implies that loopback peers are not allowed, coturn administrators may choose to not set the `denied-peer-ip` setting. The issue patched in version 4.5.2. As a workaround the addresses in the address block `0.0.0.0/8`, `[::1]` and `[::]` should be denied by default unless `--allow-loopback-peers` has been specified.
