CVE-2020-11996 6 Apache, Canonical, Debian and 3 more 8 Tomcat, Ubuntu Linux, Debian Linux and 5 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive.
CVE-2020-11993 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2023-11-07 4.3 MEDIUM 7.5 HIGH
Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.
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-2020-11945 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials).
CVE-2020-11884 5 Canonical, Debian, Fedoraproject and 2 more 35 Ubuntu Linux, Debian Linux, Fedora and 32 more 2023-11-07 6.9 MEDIUM 7.0 HIGH
In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution may occur because of a race condition, as demonstrated by code in enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur.
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-2020-11764 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 write in copyIntoFrameBuffer in ImfMisc.cpp.
CVE-2020-11763 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 std::vector out-of-bounds read and write, as demonstrated by ImfTileOffsets.cpp.
CVE-2020-11762 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 and write in DwaCompressor::uncompress in ImfDwaCompressor.cpp when handling the UNKNOWN compression case.
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-2020-11760 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 during RLE uncompression in rleUncompress in ImfRle.cpp.
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-2020-11758 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-2020-11741 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2023-11-07 6.9 MEDIUM 8.8 HIGH
An issue was discovered in xenoprof in Xen through 4.13.x, allowing guest OS users (with active profiling) to obtain sensitive information about other guests, cause a denial of service, or possibly gain privileges. For guests for which "active" profiling was enabled by the administrator, the xenoprof code uses the standard Xen shared ring structure. Unfortunately, this code did not treat the guest as a potential adversary: it trusts the guest not to modify buffer size information or modify head / tail pointers in unexpected ways. This can crash the host (DoS). Privilege escalation cannot be ruled out.
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-2020-11739 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-2020-11647 3 Debian, Opensuse, Wireshark 3 Debian Linux, Leap, Wireshark 2023-11-07 5.0 MEDIUM 7.5 HIGH
In Wireshark 3.2.0 to 3.2.2, 3.0.0 to 3.0.9, and 2.6.0 to 2.6.15, the BACapp dissector could crash. This was addressed in epan/dissectors/packet-bacapp.c by limiting the amount of recursion.
CVE-2020-11620 4 Debian, Fasterxml, Netapp and 1 more 18 Debian Linux, Jackson-databind, Active Iq Unified Manager and 15 more 2023-11-07 6.8 MEDIUM 8.1 HIGH
FasterXML jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to org.apache.commons.jelly.impl.Embedded (aka commons-jelly).
CVE-2020-11619 4 Debian, Fasterxml, Netapp and 1 more 21 Debian Linux, Jackson-databind, Active Iq Unified Manager and 18 more 2023-11-07 6.8 MEDIUM 8.1 HIGH
FasterXML jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to org.springframework.aop.config.MethodLocatingFactoryBean (aka spring-aop).
