| CVE-2020-25682 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2024-02-28 | 8.3 HIGH | 8.1 HIGH |
| A flaw was found in dnsmasq before 2.83. A buffer overflow vulnerability was discovered in the way dnsmasq extract names from DNS packets before validating them with DNSSEC data. An attacker on the network, who can create valid DNS replies, could use this flaw to cause an overflow with arbitrary data in a heap-allocated memory, possibly executing code on the machine. The flaw is in the rfc1035.c:extract_name() function, which writes data to the memory pointed by name assuming MAXDNAME*2 bytes are available in the buffer. However, in some code execution paths, it is possible extract_name() gets passed an offset from the base buffer, thus reducing, in practice, the number of available bytes that can be written in the buffer. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-25664 | 2 Fedoraproject, Imagemagick | 2 Fedora, Imagemagick | 2024-02-28 | 5.8 MEDIUM | 6.1 MEDIUM |
| In WriteOnePNGImage() of the PNG coder at coders/png.c, an improper call to AcquireVirtualMemory() and memset() allows for an out-of-bounds write later when PopShortPixel() from MagickCore/quantum-private.h is called. The patch fixes the calls by adding 256 to rowbytes. An attacker who is able to supply a specially crafted image could affect availability with a low impact to data integrity. This flaw affects ImageMagick versions prior to 6.9.10-68 and 7.0.8-68. | |||||
| CVE-2020-27814 | 2 Debian, Uclouvain | 2 Debian Linux, Openjpeg | 2024-02-28 | 6.8 MEDIUM | 7.8 HIGH |
| A heap-buffer overflow was found in the way openjpeg2 handled certain PNG format files. An attacker could use this flaw to cause an application crash or in some cases execute arbitrary code with the permission of the user running such an application. | |||||
| CVE-2020-25681 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2024-02-28 | 8.3 HIGH | 8.1 HIGH |
| A flaw was found in dnsmasq before version 2.83. A heap-based buffer overflow was discovered in the way RRSets are sorted before validating with DNSSEC data. An attacker on the network, who can forge DNS replies such as that they are accepted as valid, could use this flaw to cause a buffer overflow with arbitrary data in a heap memory segment, possibly executing code on the machine. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2021-21006 | 3 Adobe, Apple, Microsoft | 3 Photoshop, Macos, Windows | 2024-02-28 | 6.8 MEDIUM | 8.6 HIGH |
| Adobe Photoshop version 22.1 (and earlier) is affected by a heap buffer overflow vulnerability when handling a specially crafted font file.

| CVE-2020-27251 | 1 Rockwellautomation | 1 Factorytalk Linx | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| A heap overflow vulnerability exists within FactoryTalk Linx Version 6.11 and prior. This vulnerability could allow a remote, unauthenticated attacker to send malicious port ranges, which could result in remote code execution. | |||||
| CVE-2020-25683 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2024-02-28 | 7.1 HIGH | 5.9 MEDIUM |
| A flaw was found in dnsmasq before version 2.83. A heap-based buffer overflow was discovered in dnsmasq when DNSSEC is enabled and before it validates the received DNS entries. A remote attacker, who can create valid DNS replies, could use this flaw to cause an overflow in a heap-allocated memory. This flaw is caused by the lack of length checks in rfc1035.c:extract_name(), which could be abused to make the code execute memcpy() with a negative size in get_rdata() and cause a crash in dnsmasq, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2020-25674 | 2 Debian, Imagemagick | 2 Debian Linux, Imagemagick | 2024-02-28 | 4.3 MEDIUM | 5.5 MEDIUM |
| WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. The patch replaces the hardcoded 256 value with a call to MagickMin() to ensure the proper value is used. This could impact application availability when a specially crafted input file is processed by ImageMagick. This flaw affects ImageMagick versions prior to 7.0.8-68. | |||||
| CVE-2020-15800 | 1 Siemens | 132 Scalance X200-4pirt, Scalance X200-4pirt Firmware, Scalance X201-3pirt and 129 more | 2024-02-28 | 9.3 HIGH | 9.8 CRITICAL |

The webserver of the affected devices contains a vulnerability that may lead to a heap overflow condition. An attacker could cause this condition on the webserver by sending specially crafted requests. This could stop the webserver temporarily. | |||||
| CVE-2020-25667 | 1 Imagemagick | 1 Imagemagick | 2024-02-28 | 4.3 MEDIUM | 5.5 MEDIUM |
| TIFFGetProfiles() in /coders/tiff.c calls strstr() which causes a large out-of-bounds read when it searches for `"dc:format=\"image/dng\"` within `profile` due to improper string handling, when a crafted input file is provided to ImageMagick. The patch uses a StringInfo type instead of a raw C string to remedy this. This could cause an impact to availability of the application. This flaw affects ImageMagick versions prior to 7.0.9-0. | |||||
