CVE-2020-25212 – kernel: TOCTOU mismatch in the NFS client code
https://notcve.org/view.php?id=CVE-2020-25212
09 Sep 2020 — A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. Una discrepancia de TOCTOU en el código del cliente NFS en el kernel de Linux versiones anteriores a 5.8.3, podría ser usada por atacantes locales para dañar la memoria o posiblemente tener otro impacto no especificado porque una comprobación de tam... • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00021.html • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-787: Out-of-bounds Write •

CVE-2020-14364 – QEMU: usb: out-of-bounds r/w access issue while processing usb packets
https://notcve.org/view.php?id=CVE-2020-14364
31 Aug 2020 — An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host.

CVE-2020-15810 – squid: HTTP Request Smuggling could result in cache poisoning
https://notcve.org/view.php?id=CVE-2020-15810
27 Aug 2020 — An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the default), Squid relays headers containing whitespace characters to upstream servers. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00012.html • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVE-2020-15811 – squid: HTTP Request Splitting could result in cache poisoning
https://notcve.org/view.php?id=CVE-2020-15811
27 Aug 2020 — An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Splitting attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the browser cache and any downstream caches with content from an arbitrary source. Squid uses a string search instead of parsing the Transfer-Encoding header to find chunked encoding. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00012.html • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') CWE-697: Incorrect Comparison •
CVE-2020-24606 – squid: Improper input validation could result in a DoS
https://notcve.org/view.php?id=CVE-2020-24606
24 Aug 2020 — Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF.

CVE-2020-14367
https://notcve.org/view.php?id=CVE-2020-14367
24 Aug 2020 — A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony folder. The file is created during chronyd startup while still running as the root user, and when it's opened for writing, chronyd does not check for an existing symbolic link with the same file name. This flaw allows an attacker with privileged access to create a symlink with the default PID file name pointing to any destination file in the system, resulting in data loss and a denial of service due to the ... • https://bugzilla.redhat.com/show_bug.cgi?id=1870298 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVE-2020-14350 – postgresql: Uncontrolled search path element in CREATE EXTENSION

24 Aug 2020 — It was found that some PostgreSQL extensions did not use search_path safely in their installation script. An attacker with sufficient privileges could use this flaw to trick an administrator into executing a specially crafted script, during the installation or update of such extension. This affects PostgreSQL versions before 12.4, before 11.9, before 10.14, before 9.6.19, and before 9.5.23.
