| CVE-2020-25683 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2024-11-21 | 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-2020-25682 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2024-11-21 | 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-2020-25681 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2024-11-21 | 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-2020-25674 | 2 Debian, Imagemagick | 2 Debian Linux, Imagemagick | 2024-11-21 | 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-2020-25667 | 1 Imagemagick | 1 Imagemagick | 2024-11-21 | 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. | |||||
| CVE-2020-25664 | 2 Fedoraproject, Imagemagick | 2 Fedora, Imagemagick | 2024-11-21 | 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-2020-14311 | 4 Canonical, Gnu, Opensuse and 1 more | 7 Ubuntu Linux, Grub2, Leap and 4 more | 2024-11-21 | 3.6 LOW | 5.7 MEDIUM |
| There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow. | |||||
| CVE-2020-11061 | 2 Bareos, Debian | 2 Bareos, Debian Linux | 2024-11-21 | 6.0 MEDIUM | 6.0 MEDIUM |
| In Bareos Director less than or equal to 16.2.10, 17.2.9, 18.2.8, and 19.2.7, a heap overflow allows a malicious client to corrupt the director's memory via oversized digest strings sent during initialization of a verify job. Disabling verify jobs mitigates the problem. This issue is also patched in Bareos versions 19.2.8, 18.2.9 and 17.2.10. | |||||
| CVE-2020-10928 | 1 Netgear | 2 R6700, R6700 Firmware | 2024-11-21 | 4.6 MEDIUM | 8.4 HIGH |
| This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700 V1.0.4.84_10.0.58 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of string table file uploads. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the web server. Was ZDI-CAN-9767. | |||||
