| CVE-2020-27779 | 3 Fedoraproject, Gnu, Redhat | 7 Fedora, Grub2, Enterprise Linux and 4 more | 2021-05-01 | 6.9 MEDIUM | 7.5 HIGH |
| A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2021-20233 | 3 Fedoraproject, Gnu, Redhat | 7 Fedora, Grub2, Enterprise Linux and 4 more | 2021-05-01 | 7.2 HIGH | 8.2 HIGH |
| A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-10713 | 1 Gnu | 1 Grub2 | 2021-05-01 | 4.6 MEDIUM | 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-2020-29573 | 2 Gnu, Redhat | 2 Glibc, Enterprise Linux | 2021-01-26 | 5.0 MEDIUM | 7.5 HIGH |
| sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words, the reference to 2.23 is intentional despite the mention of "Fixed for glibc 2.33" in the 26649 reference. | |||||
| CVE-2019-1010023 | 1 Gnu | 1 Glibc | 2020-11-16 | 6.8 MEDIUM | 8.8 HIGH |
| ** DISPUTED ** GNU Libc current is affected by: Re-mapping current loaded library with malicious ELF file. The impact is: In worst case attacker may evaluate privileges. The component is: libld. The attack vector is: Attacker sends 2 ELF files to victim and asks to run ldd on it. ldd execute code. NOTE: Upstream comments indicate "this is being treated as a non-security bug and no real threat." | |||||
| CVE-2016-3706 | 2 Gnu, Opensuse | 2 Glibc, Opensuse | 2020-10-29 | 5.0 MEDIUM | 7.5 HIGH |
| Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in the GNU C Library (aka glibc or libc6) allows remote attackers to cause a denial of service (crash) via vectors involving hostent conversion. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-4458. | |||||
| CVE-2020-24659 | 2 Fedoraproject, Gnu | 2 Fedora, Gnutls | 2020-10-26 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure. | |||||
| CVE-2017-16997 | 2 Gnu, Redhat | 4 Glibc, Enterprise Linux Desktop, Enterprise Linux Server and 1 more | 2020-10-15 | 9.3 HIGH | 7.8 HIGH |
| elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26 mishandles RPATH and RUNPATH containing $ORIGIN for a privileged (setuid or AT_SECURE) program, which allows local users to gain privileges via a Trojan horse library in the current working directory, related to the fillin_rpath and decompose_rpath functions. This is associated with misinterpretion of an empty RPATH/RUNPATH token as the "./" directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very uncommon; most likely, no such program is shipped with any common Linux distribution. | |||||
| CVE-2017-1000366 | 8 Debian, Gnu, Mcafee and 5 more | 20 Debian Linux, Glibc, Web Gateway and 17 more | 2020-10-15 | 7.2 HIGH | 7.8 HIGH |
| glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier. | |||||
| CVE-2019-15847 | 2 Gnu, Opensuse | 2 Gcc, Leap | 2020-09-17 | 5.0 MEDIUM | 7.5 HIGH |
| The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the __builtin_darn intrinsic into a single call, thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example, within a single execution of a program, the output of every __builtin_darn() call may be the same. | |||||
| CVE-2017-8804 | 1 Gnu | 1 Glibc | 2020-08-26 | 7.8 HIGH | 7.5 HIGH |
| ** DISPUTED ** The xdr_bytes and xdr_string functions in the GNU C Library (aka glibc or libc6) 2.25 mishandle failures of buffer deserialization, which allows remote attackers to cause a denial of service (virtual memory allocation, or memory consumption if an overcommit setting is not used) via a crafted UDP packet to port 111, a related issue to CVE-2017-8779. NOTE: [Information provided from upstream and references] | |||||
| CVE-2019-15767 | 1 Gnu | 1 Chess | 2020-08-24 | 6.8 MEDIUM | 7.8 HIGH |

| CVE-2019-16200 | 1 Gnu | 1 Serveez | 2020-08-24 | 5.0 MEDIUM | 7.5 HIGH |
| GNU Serveez through 0.2.2 has an Information Leak. An attacker may send an HTTP POST request to the /cgi-bin/reader URI. The attacker must include a Content-length header with a large positive value that, when represented in 32 bit binary, evaluates to a negative number. The problem exists in the http_cgi_write function under http-cgi.c; however, exploitation might show svz_envblock_add in libserveez/passthrough.c as the location of the heap-based buffer over-read. | |||||
| CVE-2019-9192 | 1 Gnu | 1 Glibc | 2020-08-24 | 5.0 MEDIUM | 7.5 HIGH |
| ** DISPUTED ** In the GNU C Library (aka glibc or libc6) through 2.29, check_dst_limits_calc_pos_1 in posix/regexec.c has Uncontrolled Recursion, as demonstrated by '(|)(\\1\\1)*' in grep, a different issue than CVE-2018-20796. NOTE: the software maintainer disputes that this is a vulnerability because the behavior occurs only with a crafted pattern. | |||||
| CVE-2019-11640 | 1 Gnu | 1 Recutils | 2020-08-24 | 6.8 MEDIUM | 8.8 HIGH |
| An issue was discovered in GNU recutils 1.8. There is a heap-based buffer overflow in the function rec_fex_parse_str_simple at rec-fex.c in librec.a. | |||||

| CVE-2019-18862 | 1 Gnu | 1 Mailutils | 2020-08-24 | 4.6 MEDIUM | 7.8 HIGH |
| maidag in GNU Mailutils before 3.8 is installed setuid and allows local privilege escalation in the url mode. | |||||
| CVE-2018-20483 | 1 Gnu | 1 Wget | 2020-08-24 | 2.1 LOW | 7.8 HIGH |
| set_file_metadata in xattr.c in GNU Wget before 1.20.1 stores a file's origin URL in the user.xdg.origin.url metadata attribute of the extended attributes of the downloaded file, which allows local users to obtain sensitive information (e.g., credentials contained in the URL) by reading this attribute, as demonstrated by getfattr. This also applies to Referer information in the user.xdg.referrer.url metadata attribute. According to 2016-07-22 in the Wget ChangeLog, user.xdg.origin.url was partially based on the behavior of fwrite_xattr in tool_xattr.c in curl. | |||||
