CVE-2020-11984 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2023-11-07 7.5 HIGH 9.8 CRITICAL
Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE
CVE-2020-11759 5 Apple, Canonical, Debian and 2 more 11 Icloud, Ipados, Iphone Os and 8 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in OpenEXR before 2.4.1. Because of integer overflows in CompositeDeepScanLine::Data::handleDeepFrameBuffer and readSampleCountForLineBlock, an attacker can write to an out-of-bounds pointer.
CVE-2020-11739 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2023-11-07 6.9 MEDIUM 7.8 HIGH
An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service or possibly gain privileges because of missing memory barriers in read-write unlock paths. The read-write unlock paths don't contain a memory barrier. On Arm, this means a processor is allowed to re-order the memory access with the preceding ones. In other words, the unlock may be seen by another processor before all the memory accesses within the "critical" section. As a consequence, it may be possible to have a writer executing a critical section at the same time as readers or another writer. In other words, many of the assumptions (e.g., a variable cannot be modified after a check) in the critical sections are not safe anymore. The read-write locks are used in hypercalls (such as grant-table ones), so a malicious guest could exploit the race. For instance, there is a small window where Xen can leak memory if XENMAPSPACE_grant_table is used concurrently. A malicious guest may be able to leak memory, or cause a hypervisor crash resulting in a Denial of Service (DoS). Information leak and privilege escalation cannot be excluded.
CVE-2020-11740 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2023-11-07 2.1 LOW 5.5 MEDIUM
An issue was discovered in xenoprof in Xen through 4.13.x, allowing guest OS users (without active profiling) to obtain sensitive information about other guests. Unprivileged guests can request to map xenoprof buffers, even if profiling has not been enabled for those guests. These buffers were not scrubbed.
CVE-2020-12888 6 Canonical, Debian, Fedoraproject and 3 more 39 Ubuntu Linux, Debian Linux, Fedora and 36 more 2023-11-07 4.7 MEDIUM 5.3 MEDIUM
The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.
CVE-2020-11810 3 Debian, Fedoraproject, Openvpn 3 Debian Linux, Fedora, Openvpn 2023-11-07 4.3 MEDIUM 3.7 LOW
An issue was discovered in OpenVPN 2.4.x before 2.4.9. An attacker can inject a data channel v2 (P_DATA_V2) packet using a victim's peer-id. Normally such packets are dropped, but if this packet arrives before the data channel crypto parameters have been initialized, the victim's connection will be dropped. This requires careful timing due to the small time window (usually within a few seconds) between the victim client connection starting and the server PUSH_REPLY response back to the client. This attack will only work if Negotiable Cipher Parameters (NCP) is in use.
CVE-2020-11765 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipados, Iphone Os and 9 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in OpenEXR before 2.4.1. There is an off-by-one error in use of the ImfXdr.h read function by DwaCompressor::Classifier::Classifier, leading to an out-of-bounds read.
CVE-2020-11761 5 Apple, Canonical, Debian and 2 more 11 Icloud, Ipados, Iphone Os and 8 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read during Huffman uncompression, as demonstrated by FastHufDecoder::refill in ImfFastHuf.cpp.
CVE-2020-12663 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
Unbound before 1.10.1 has an infinite loop via malformed DNS answers received from upstream servers.
CVE-2020-11758 6 Apple, Canonical, Debian and 3 more 12 Icloud, Ipados, Iphone Os and 9 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read in ImfOptimizedPixelReading.h.
CVE-2020-12100 4 Canonical, Debian, Dovecot and 1 more 4 Ubuntu Linux, Debian Linux, Dovecot and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
In Dovecot before 2.3.11.3, uncontrolled recursion in submission, lmtp, and lda allows remote attackers to cause a denial of service (resource consumption) via a crafted e-mail message with deeply nested MIME parts.
CVE-2020-11078 3 Debian, Fedoraproject, Httplib2 Project 3 Debian Linux, Fedora, Httplib2 2023-11-07 4.3 MEDIUM 6.8 MEDIUM
In httplib2 before version 0.18.0, an attacker controlling unescaped part of uri for `httplib2.Http.request()` could change request headers and body, send additional hidden requests to same server. This vulnerability impacts software that uses httplib2 with uri constructed by string concatenation, as opposed to proper urllib building with escaping. This has been fixed in 0.18.0.
CVE-2020-10995 4 Debian, Fedoraproject, Opensuse and 1 more 5 Debian Linux, Fedora, Backports Sle and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
PowerDNS Recursor from 4.1.0 up to and including 4.3.0 does not sufficiently defend against amplification attacks. An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS services to attack third party authoritative name servers. The attack uses a crafted reply by an authoritative name server to amplify the resulting traffic between the recursive and other authoritative name servers. Both types of service can suffer degraded performance as an effect. This is triggered by random subdomains in the NSDNAME in NS records. PowerDNS Recursor 4.1.16, 4.2.2 and 4.3.1 contain a mitigation to limit the impact of this DNS protocol issue.
CVE-2020-10936 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-11-07 7.2 HIGH 7.8 HIGH
Sympa before 6.2.56 allows privilege escalation.
CVE-2020-11080 6 Debian, Fedoraproject, Nghttp2 and 3 more 10 Debian Linux, Fedora, Nghttp2 and 7 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection.
CVE-2020-11100 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 6.5 MEDIUM 8.8 HIGH
In hpack_dht_insert in hpack-tbl.c in the HPACK decoder in HAProxy 1.8 through 2.x before 2.1.4, a remote attacker can write arbitrary bytes around a certain location on the heap via a crafted HTTP/2 request, possibly causing remote code execution.
CVE-2020-11096 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 6.4 MEDIUM 6.5 MEDIUM
In FreeRDP before version 2.1.2, there is a global OOB read in update_read_cache_bitmap_v3_order. As a workaround, one can disable bitmap cache with -bitmap-cache (default). This is fixed in version 2.1.2.
CVE-2020-11098 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 5.8 MEDIUM 6.5 MEDIUM
In FreeRDP before version 2.1.2, there is an out-of-bound read in glyph_cache_put. This affects all FreeRDP clients with `+glyph-cache` option enabled This is fixed in version 2.1.2.
CVE-2020-11097 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 5.5 MEDIUM 5.4 MEDIUM
In FreeRDP before version 2.1.2, an out of bounds read occurs resulting in accessing a memory location that is outside of the boundaries of the static array PRIMARY_DRAWING_ORDER_FIELD_BYTES. This is fixed in version 2.1.2.
CVE-2020-10745 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2023-11-07 7.8 HIGH 7.5 HIGH
A flaw was found in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4 in the way it processed NetBios over TCP/IP. This flaw allows a remote attacker could to cause the Samba server to consume excessive CPU use, resulting in a denial of service. This highest threat from this vulnerability is to system availability.
