| CVE-2020-14310 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-08-04 | 5.7 Medium |
| There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow. | ||||
| CVE-2020-14308 | 3 Gnu, Opensuse, Redhat | 7 Grub2, Leap, Enterprise Linux and 4 more | 2024-08-04 | 6.4 Medium |
| In grub2 versions before 2.06 the grub memory allocator doesn't check for possible arithmetic overflows on the requested allocation size. This leads the function to return invalid memory allocations which can be further used to cause possible integrity, confidentiality and availability impacts during the boot process. | ||||
| CVE-2020-14311 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-08-04 | 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-2020-14150 | 1 Gnu | 1 Bison | 2024-08-04 | 5.5 Medium |
| GNU Bison before 3.5.4 allows attackers to cause a denial of service (application crash). NOTE: there is a risk only if Bison is used with untrusted input, and an observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug reports were intended to show that a crash may occur in Bison itself, not that a crash may occur in code that is generated by Bison. | ||||
| CVE-2020-13777 | 5 Canonical, Debian, Fedoraproject and 2 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-08-04 | 7.4 High |
| GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application. | ||||
| CVE-2020-12108 | 6 Canonical, Debian, Fedoraproject and 3 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-08-04 | 6.5 Medium |
| /options/mailman in GNU Mailman before 2.1.31 allows Arbitrary Content Injection. | ||||
| CVE-2020-12137 | 6 Canonical, Debian, Fedoraproject and 3 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-08-04 | 6.1 Medium |
| GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts. This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the MIME type should have been text/html, and execute JavaScript code. | ||||
| CVE-2020-11501 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-08-04 | 7.4 High |
| GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol. | ||||
| CVE-2020-10713 | 5 Debian, Gnu, Opensuse and 2 more | 10 Debian Linux, Grub2, Leap and 7 more | 2024-08-04 | 8.2 High |
| A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access to the system such as gaining physical access, obtain the ability to alter a pxe-boot network, or have remote access to a networked system with root access. With this access, an attacker could then craft a string to cause a buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-10029 | 7 Canonical, Debian, Fedoraproject and 4 more | 18 Ubuntu Linux, Debian Linux, Fedora and 15 more | 2024-08-04 | 5.5 Medium |
| The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c. | ||||
| CVE-2020-9366 | 1 Gnu | 1 Screen | 2024-08-04 | 9.8 Critical |
| A buffer overflow was found in the way GNU Screen before 4.8.0 treated the special escape OSC 49. Specially crafted output, or a special program, could corrupt memory and crash Screen or possibly have unspecified other impact. | ||||
| CVE-2020-6614 | 2 Gnu, Opensuse | 3 Libredwg, Backports Sle, Leap | 2024-08-04 | 8.1 High |
| GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in bfr_read in decode.c. | ||||
| CVE-2020-6611 | 2 Gnu, Opensuse | 3 Libredwg, Backports Sle, Leap | 2024-08-04 | 6.5 Medium |
| GNU LibreDWG 0.9.3.2564 has a NULL pointer dereference in get_next_owned_entity in dwg.c. | ||||
| CVE-2020-6612 | 2 Gnu, Opensuse | 3 Libredwg, Backports Sle, Leap | 2024-08-04 | 8.1 High |
| GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in copy_compressed_bytes in decode_r2007.c. | ||||
| CVE-2020-6613 | 2 Gnu, Opensuse | 3 Libredwg, Backports Sle, Leap | 2024-08-04 | 8.1 High |
| GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in bit_search_sentinel in bits.c. | ||||
| CVE-2020-6615 | 2 Gnu, Opensuse | 3 Libredwg, Backports Sle, Leap | 2024-08-04 | 6.5 Medium |
| GNU LibreDWG 0.9.3.2564 has an invalid pointer dereference in dwg_dynapi_entity_value in dynapi.c (dynapi.c is generated by gen-dynapi.pl). | ||||
| CVE-2020-6610 | 2 Gnu, Opensuse | 3 Libredwg, Backports, Leap | 2024-08-04 | 6.5 Medium |
| GNU LibreDWG 0.9.3.2564 has an attempted excessive memory allocation in read_sections_map in decode_r2007.c. | ||||
| CVE-2020-6609 | 2 Gnu, Opensuse | 3 Libredwg, Backports Sle, Leap | 2024-08-04 | 8.8 High |
| GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in read_pages_map in decode_r2007.c. | ||||
| CVE-2020-6096 | 3 Debian, Fedoraproject, Gnu | 3 Debian Linux, Fedora, Glibc | 2024-08-04 | 8.1 High |
| An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc 2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the 'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data. | ||||
| CVE-2020-1752 | 5 Canonical, Debian, Gnu and 2 more | 10 Ubuntu Linux, Debian Linux, Glibc and 7 more | 2024-08-04 | 7 High |
| A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32. | ||||
