An integer buffer overflow in the Nginx webserver of ExpressVPN Router version 1 allows remote attackers to obtain sensitive information when the server running as reverse proxy via specially crafted request.
CVE-2020-29040 1 Xen 1 Xen 2024-11-21 8.8 High
An issue was discovered in Xen through 4.14.x allowing x86 HVM guest OS users to cause a denial of service (stack corruption), cause a data leak, or possibly gain privileges because of an off-by-one error. NOTE: this issue is caused by an incorrect fix for CVE-2020-27671.
CVE-2020-28895 2 Oracle, Windriver 2 Communications Eagle, Vxworks 2024-11-21 7.3 High
In Wind River VxWorks, memory allocator has a possible overflow in calculating the memory block's size to be allocated by calloc(). As a result, the actual memory allocated is smaller than the buffer size specified by the arguments, leading to memory corruption.
CVE-2020-28371 1 Readytalk 1 Avian 2024-11-21 9.8 Critical
An issue was discovered in ReadyTalk Avian 1.2.0 before 2020-10-27. The FileOutputStream.write() method in FileOutputStream.java has a boundary check to prevent out-of-bounds memory read/write operations. However, an integer overflow leads to bypassing this check and achieving the out-of-bounds access. NOTE: This vulnerability only affects products that are no longer supported by the maintainer
CVE-2020-28248 1 Png-img Project 1 Png-img 2024-11-21 8.8 High
An integer overflow in the PngImg::InitStorage_() function of png-img before 3.1.0 leads to an under-allocation of heap memory and subsequently an exploitable heap-based buffer overflow when loading a crafted PNG file.
CVE-2020-28194 1 Accel-ppp 1 Accel-ppp 2024-11-21 9.8 Critical
Variable underflow exists in accel-ppp radius/packet.c when receiving a RADIUS vendor-specific attribute with length field is less than 2. It has an impact only when the attacker controls the RADIUS server, which can lead to arbitrary code execution.
CVE-2020-28020 1 Exim 1 Exim 2024-11-21 9.8 Critical
Exim 4 before 4.92 allows Integer Overflow to Buffer Overflow, in which an unauthenticated remote attacker can execute arbitrary code by leveraging the mishandling of continuation lines during header-length restriction.
CVE-2020-28017 1 Exim 1 Exim 2024-11-21 9.8 Critical
Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow in receive_add_recipient via an e-mail message with fifty million recipients. NOTE: remote exploitation may be difficult because of resource consumption.
CVE-2020-28009 1 Exim 1 Exim 2024-11-21 7.8 High
Exim 4 before 4.94.2 allows Integer Overflow to Buffer Overflow because get_stdinput allows unbounded reads that are accompanied by unbounded increases in a certain size variable. NOTE: exploitation may be impractical because of the execution time needed to overflow (multiple days).
CVE-2020-27945 1 Apple 2 Mac Os X, Macos 2024-11-21 7.8 High
An integer overflow was addressed with improved input validation. This issue is fixed in macOS Big Sur 11.2, Security Update 2021-001 Catalina, Security Update 2021-001 Mojave, macOS Big Sur 11.0.1. Processing maliciously crafted web content may lead to arbitrary code execution.
CVE-2020-27911 1 Apple 7 Icloud, Ipados, Iphone Os and 4 more 2024-11-21 7.8 High
An integer overflow was addressed through improved input validation. This issue is fixed in macOS Big Sur 11.0.1, watchOS 7.1, iOS 14.2 and iPadOS 14.2, iCloud for Windows 11.5, tvOS 14.2, iTunes 12.11 for Windows. A remote attacker may be able to cause unexpected application termination or arbitrary code execution.
CVE-2020-27906 1 Apple 1 Macos 2024-11-21 8.8 High
Multiple integer overflows were addressed with improved input validation. This issue is fixed in macOS Big Sur 11.0.1. A remote attacker may be able to cause unexpected application termination or heap corruption.
CVE-2020-27813 3 Debian, Gorillatoolkit, Redhat 4 Debian Linux, Websocket, Container Native Virtualization and 1 more 2024-11-21 7.5 High
An integer overflow vulnerability exists with the length of websocket frames received via a websocket connection. An attacker would use this flaw to cause a denial of service attack on an HTTP Server allowing websocket connections.
CVE-2020-27793 1 Radare 1 Radare2 2024-11-21 7.5 High
An off-by-one overflow flaw was found in radare2 due to mismatched array length in core_java.c. This could allow an attacker to cause a crash, and perform a denail of service attack.
CVE-2020-27776 2 Imagemagick, Redhat 2 Imagemagick, Enterprise Linux 2024-11-21 3.3 Low
A flaw was found in ImageMagick in MagickCore/statistic.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned long. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-27775 3 Debian, Imagemagick, Redhat 3 Debian Linux, Imagemagick, Enterprise Linux 2024-11-21 3.3 Low
A flaw was found in ImageMagick in MagickCore/quantum.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-27774 3 Debian, Imagemagick, Redhat 3 Debian Linux, Imagemagick, Enterprise Linux 2024-11-21 3.3 Low
A flaw was found in ImageMagick in MagickCore/statistic.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of a too large shift for 64-bit type `ssize_t`. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-27773 3 Debian, Imagemagick, Redhat 3 Debian Linux, Imagemagick, Enterprise Linux 2024-11-21 3.3 Low
A flaw was found in ImageMagick in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type `unsigned char` or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
