CVE-2020-16592 3 Fedoraproject, Gnu, Netapp 3 Fedora, Binutils, Ontap Select Deploy Administration Utility 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
A use after free issue exists in the Binary File Descriptor (BFD) library (aka libbfd) in GNU Binutils 2.34 in bfd_hash_lookup, as demonstrated in nm-new, that can cause a denial of service via a crafted file.
CVE-2020-16591 2 Gnu, Netapp 2 Binutils, Ontap Select Deploy Administration Utility 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
A Denial of Service vulnerability exists in the Binary File Descriptor (BFD) in GNU Binutils 2.35 due to an invalid read in process_symbol_table, as demonstrated in readeif.
CVE-2020-16590 2 Gnu, Netapp 2 Binutils, Ontap Select Deploy Administration Utility 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
A double free vulnerability exists in the Binary File Descriptor (BFD) (aka libbrd) in GNU Binutils 2.35 in the process_symbol_table, as demonstrated in readelf, via a crafted file.
CVE-2020-14372 4 Fedoraproject, Gnu, Netapp and 1 more 9 Fedora, Grub2, Cloud Backup and 6 more 2023-11-07 6.2 MEDIUM 7.5 HIGH
A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability.
CVE-2020-14311 4 Canonical, Gnu, Opensuse and 1 more 7 Ubuntu Linux, Grub2, Leap and 4 more 2023-11-07 3.6 LOW 6.0 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-2020-14310 4 Canonical, Gnu, Opensuse and 1 more 7 Ubuntu Linux, Grub2, Leap and 4 more 2023-11-07 3.6 LOW 6.0 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-2020-13777 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-11-07 5.8 MEDIUM 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-2020-12137 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 4.3 MEDIUM 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-2020-12108 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
/options/mailman in GNU Mailman before 2.1.31 allows Arbitrary Content Injection.
CVE-2020-11501 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 5.8 MEDIUM 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-2020-10029 6 Canonical, Debian, Fedoraproject and 3 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2023-11-07 2.1 LOW 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-2019-9923 2 Gnu, Opensuse 2 Tar, Leap 2023-11-07 5.0 MEDIUM 7.5 HIGH
pax_decode_header in sparse.c in GNU Tar before 1.32 had a NULL pointer dereference when parsing certain archives that have malformed extended headers.
CVE-2019-9211 3 Fedoraproject, Gnu, Suse 4 Fedora, Pspp, Backports and 1 more 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
There is a reachable assertion abort in the function write_long_string_missing_values() in data/sys-file-writer.c in libdata.a in GNU PSPP 1.2.0 that will lead to denial of service.
CVE-2019-9169 4 Canonical, Gnu, Mcafee and 1 more 6 Ubuntu Linux, Glibc, Web Gateway and 3 more 2023-11-07 7.5 HIGH 9.8 CRITICAL
In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-based buffer over-read via an attempted case-insensitive regular-expression match.
CVE-2019-3836 3 Fedoraproject, Gnu, Opensuse 3 Fedora, Gnutls, Leap 2023-11-07 5.0 MEDIUM 7.5 HIGH
It was discovered in gnutls before version 3.6.7 upstream that there is an uninitialized pointer access in gnutls versions 3.6.3 or later which can be triggered by certain post-handshake messages.
CVE-2019-3829 2 Fedoraproject, Gnu 2 Fedora, Gnutls 2023-11-07 5.0 MEDIUM 7.5 HIGH
A vulnerability was found in gnutls versions from 3.5.8 before 3.6.7. A memory corruption (double free) vulnerability in the certificate verification API. Any client or server application that verifies X.509 certificates with GnuTLS 3.5.8 or later is affected.
CVE-2019-25051 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Aspell 2023-11-07 4.6 MEDIUM 7.8 HIGH
objstack in GNU Aspell 0.60.8 has a heap-based buffer overflow in acommon::ObjStack::dup_top (called from acommon::StringMap::add and acommon::Config::lookup_list).
CVE-2019-19126 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-11-07 2.1 LOW 3.3 LOW
On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.
CVE-2019-18397 2 Debian, Gnu 2 Debian Linux, Fribidi 2023-11-07 6.8 MEDIUM 7.8 HIGH
A buffer overflow in the fribidi_get_par_embedding_levels_ex() function in lib/fribidi-bidi.c of GNU FriBidi through 1.0.7 allows an attacker to cause a denial of service or possibly execute arbitrary code by delivering crafted text content to a user, when this content is then rendered by an application that uses FriBidi for text layout calculations. Examples include any GNOME or GTK+ based application that uses Pango for text layout, as this internally uses FriBidi for bidirectional text layout. For example, the attacker can construct a crafted text file to be opened in GEdit, or a crafted IRC message to be viewed in HexChat.
CVE-2019-18276 3 Gnu, Netapp, Oracle 5 Bash, Hci Management Node, Oncommand Unified Manager and 2 more 2023-11-07 7.2 HIGH 7.8 HIGH
An issue was discovered in disable_priv_mode in shell.c in GNU Bash through 5.0 patch 11. By default, if Bash is run with its effective UID not equal to its real UID, it will drop privileges by setting its effective UID to its real UID. However, it does so incorrectly. On Linux and other systems that support "saved UID" functionality, the saved UID is not dropped. An attacker with command execution in the shell can use "enable -f" for runtime loading of a new builtin, which can be a shared object that calls setuid() and therefore regains privileges. However, binaries running with an effective UID of 0 are unaffected.
