  - During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean     Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform     electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.
    *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected,     but products built on top of it might. This vulnerability affects Firefox < 78. (CVE-2020-12402)

  - A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using     multi-part Chacha20, it could cause out-of-bounds reads. This issue was fixed by explicitly disabling     multi-part ChaCha20 (which was not functioning correctly) and strictly enforcing tag length. The highest     threat from this vulnerability is to confidentiality and system availability. (CVE-2020-12403)

  - When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which     leaked partial information about the nonce used during signature generation. Given an electro-magnetic     trace of a few signature generations, the private key could have been computed. This vulnerability affects     Firefox < 80 and Firefox for Android < 80. (CVE-2020-6829)

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4082 advisory.

  - An issue was discovered in Squid before 4.10. It allows a crafted FTP server to trigger disclosure of     sensitive information from heap memory, such as information associated with other users' sessions or non-     Squid processes. (CVE-2019-12528)

  - An issue was discovered in http/ContentLengthInterpreter.cc in Squid before 4.12 and 5.x before 5.0.3. A     Request Smuggling and Poisoning attack can succeed against the HTTP cache. The client sends an HTTP     request with a Content-Length header containing +\ - or an uncommon shell whitespace character prefix     to the length field-value. (CVE-2020-15049)

  - 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. When this occurs as a     prefix to a Content-Length header, the frame length specified will be ignored by Squid (allowing for a     conflicting length to be used from another Content-Length header) but relayed upstream. (CVE-2020-15810)

  - 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. This allows an attacker to hide a second request     inside Transfer-Encoding: it is interpreted by Squid as chunked and split out into a second request     delivered upstream. Squid will then deliver two distinct responses to the client, corrupting any     downstream caches. (CVE-2020-15811)

  - 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-2020-24606)

  - An issue was discovered in Squid before 4.10. Due to incorrect input validation, it can interpret crafted     HTTP requests in unexpected ways to access server resources prohibited by earlier security filters.
    (CVE-2020-8449)

  - An issue was discovered in Squid before 4.10. Due to incorrect buffer management, a remote client can     cause a buffer overflow in a Squid instance acting as a reverse proxy. (CVE-2020-8450)

  - In the Android kernel in the video driver there is a use after free due to a race condition. This could     lead to local escalation of privilege with no additional execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9458)

  - There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of     ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device     file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed,     it can cause an exploitable condition as the process wakes up to terminate and clean all attached files.
    The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the     inode. (CVE-2020-10690)

  - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an     attacker with a local account to crash a trivial program and exfiltrate private kernel data.
    (CVE-2020-10732)

  - A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS     client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause     a kernel panic. The highest threat from this vulnerability is to data confidentiality and system     availability. (CVE-2020-10742)

  - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it     incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly     only validate the first netlink message in the skb and allow or deny the rest of the messages within the     skb with the granted permission without further processing. (CVE-2020-10751)

  - In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family     field, which might allow attackers to trigger kernel stack corruption via crafted system calls.
    (CVE-2020-10942)

  - An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-     based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-     aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the     issue is a bug in parsing mount options which can only be specified by a privileged user, so triggering     the bug does not grant any powers not already held. (CVE-2020-11565)

  - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)

  - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in     a different security domain. Exploitation limitations include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where signals to a parent process present a substantial     operational threat. (CVE-2020-12826)

  - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection     tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote     user to crash the system, causing a denial of service. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-14305)

  - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN     and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't     correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would     allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this     vulnerability is to data confidentiality. (CVE-2020-1749)

  - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest     when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into     accessing sensitive L1 resources that should be inaccessible to the L2 guest. (CVE-2020-2732)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in     drivers/tty/vt/vt.c. (CVE-2020-8647)

  - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical     Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of     symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only     affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own     home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to     read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a     cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent     client connection came from an attacker-chosen uid, allowing authentication bypass.
