| CVE-2017-13090 | 3 Debian, Gnu, Redhat | 3 Debian Linux, Wget, Enterprise Linux | 2024-09-16 | N/A |
| The retr.c:fd_read_body() function is called when processing OK responses. When the response is sent chunked in wget before 1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to read the chunk in pieces of 8192 bytes by using the MIN() macro, but ends up passing the negative chunk length to retr.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument. The attacker can corrupt malloc metadata after the allocated buffer. | ||||
| CVE-2023-4001 | 3 Fedoraproject, Gnu, Redhat | 4 Fedora, Grub2, Enterprise Linux and 1 more | 2024-09-16 | 6.8 Medium |
| An authentication bypass flaw was found in GRUB due to the way that GRUB uses the UUID of a device to search for the configuration file that contains the password hash for the GRUB password protection feature. An attacker capable of attaching an external drive such as a USB stick containing a file system with a duplicate UUID (the same as in the "/boot/" file system) can bypass the GRUB password protection feature on UEFI systems, which enumerate removable drives before non-removable ones. This issue was introduced in a downstream patch in Red Hat's version of grub2 and does not affect the upstream package. | ||||
| CVE-2017-12455 | 1 Gnu | 1 Binutils | 2024-09-16 | N/A |
| The evax_bfd_print_emh function in vms-alpha.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29 and earlier, allows remote attackers to cause an out of bounds heap read via a crafted vms alpha file. | ||||
| CVE-2017-17426 | 1 Gnu | 1 Glibc | 2024-09-16 | N/A |
| The malloc function in the GNU C Library (aka glibc or libc6) 2.26 could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZE_MAX, potentially leading to a subsequent heap overflow. This occurs because the per-thread cache (aka tcache) feature enables a code path that lacks an integer overflow check. | ||||
| CVE-2017-12454 | 1 Gnu | 1 Binutils | 2024-09-16 | N/A |
| The _bfd_vms_slurp_egsd function in bfd/vms-alpha.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29 and earlier, allows remote attackers to cause an arbitrary memory read via a crafted vms alpha file. | ||||
| CVE-2010-3192 | 1 Gnu | 1 Glibc | 2024-09-16 | N/A |
| Certain run-time memory protection mechanisms in the GNU C Library (aka glibc or libc6) print argv[0] and backtrace information, which might allow context-dependent attackers to obtain sensitive information from process memory by executing an incorrect program, as demonstrated by a setuid program that contains a stack-based buffer overflow error, related to the __fortify_fail function in debug/fortify_fail.c, and the __stack_chk_fail (aka stack protection) and __chk_fail (aka FORTIFY_SOURCE) implementations. | ||||
| CVE-2024-1048 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Grub2, Enterprise Linux | 2024-09-16 | 3.3 Low |
| A flaw was found in the grub2-set-bootflag utility of grub2. After the fix of CVE-2019-14865, grub2-set-bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv file. If the program is killed before the rename operation, the temporary file will not be removed and may fill the filesystem when invoked multiple times, resulting in a filesystem out of free inodes or blocks. | ||||
| CVE-2023-4693 | 2 Gnu, Redhat | 2 Grub2, Enterprise Linux | 2024-09-16 | 5.3 Medium |
| An out-of-bounds read flaw was found on grub2's NTFS filesystem driver. This issue may allow a physically present attacker to present a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack allows sensitive data cached in memory or EFI variable values to be leaked, presenting a high Confidentiality risk. | ||||
| CVE-2023-4692 | 2 Gnu, Redhat | 2 Grub2, Enterprise Linux | 2024-09-16 | 7.5 High |
| An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub's heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved. | ||||
| CVE-2023-4813 | 4 Fedoraproject, Gnu, Netapp and 1 more | 23 Fedora, Glibc, Active Iq Unified Manager and 20 more | 2024-09-16 | 5.9 Medium |
| A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. | ||||
| CVE-2023-4806 | 3 Fedoraproject, Gnu, Redhat | 24 Fedora, Glibc, Codeready Linux Builder Eus and 21 more | 2024-09-16 | 5.9 Medium |
| A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags. | ||||
| CVE-2023-4527 | 4 Fedoraproject, Gnu, Netapp and 1 more | 32 Fedora, Glibc, H300s and 29 more | 2024-09-16 | 6.5 Medium |
| A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash. | ||||
| CVE-2024-0567 | 5 Debian, Fedoraproject, Gnu and 2 more | 9 Debian Linux, Fedora, Gnutls and 6 more | 2024-09-16 | 7.5 High |
| A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack. | ||||
| CVE-2024-0553 | 3 Fedoraproject, Gnu, Redhat | 6 Fedora, Gnutls, Enterprise Linux and 3 more | 2024-09-16 | 7.5 High |
| A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981. | ||||
| CVE-2023-5981 | 3 Fedoraproject, Gnu, Redhat | 7 Fedora, Gnutls, Enterprise Linux and 4 more | 2024-09-16 | 5.9 Medium |
| A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. | ||||
| CVE-2023-5156 | 2 Gnu, Redhat | 2 Glibc, Enterprise Linux | 2024-09-14 | 7.5 High |
| A flaw was found in the GNU C Library. A recent fix for CVE-2023-4806 introduced the potential for a memory leak, which may result in an application crash. | ||||
| CVE-2023-4949 | 2 Gnu, Xen | 2 Grub, Xen | 2024-09-03 | 8.1 High |
| An attacker with local access to a system (either through a disk or external drive) can present a modified XFS partition to grub-legacy in such a way to exploit a memory corruption in grub’s XFS file system implementation. | ||||
| CVE-2022-1271 | 4 Debian, Gnu, Redhat and 1 more | 8 Debian Linux, Gzip, Enterprise Linux and 5 more | 2024-08-26 | 8.8 High |
| An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system. | ||||
| CVE-2022-2601 | 3 Fedoraproject, Gnu, Redhat | 13 Fedora, Grub2, Enterprise Linux and 10 more | 2024-08-22 | 8.6 High |
| A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism. | ||||
| CVE-2024-38428 | 2 Gnu, Redhat | 6 Wget, Enterprise Linux, Rhel Aus and 3 more | 2024-08-08 | 9.1 Critical |
| url.c in GNU Wget through 1.24.5 mishandles semicolons in the userinfo subcomponent of a URI, and thus there may be insecure behavior in which data that was supposed to be in the userinfo subcomponent is misinterpreted to be part of the host subcomponent. | ||||
