The string component in the GNU C Library (aka glibc or libc6) through 2.28 when running on the x32 architecture incorrectly attempts to use a 64-bit register for size_t in assembly codes which can lead to a segmentation fault or possibly unspecified other impact as demonstrated by a crash in __memmove_avx_unaligned_erms in sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S during a memcpy.

GNU gdb All versions is affected by: Buffer Overflow - Out of bound memory access. The impact is: Deny of Service, Memory Disclosure, and Possible Code Execution. The component is: The main gdb module. The attack vector is: Open an ELF for debugging. The fixed version is: Not fixed yet.

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.

ALPINE-CVE-2020-14365

A flaw was found in the Ansible Engine, in ansible-engine 2.8.x before 2.8.15 and ansible-engine 2.9.x before 2.9.13, when installing packages using the dnf module. GPG signatures are ignored during installation even when disablegpgcheck is set to False, which is the default behavior. This flaw...

Denial Of Service (DoS)

binutils:bionic is vulnerable to denial of service DoS. The getcount function in cplus-dem.c in GNU libiberty allows remote attackers to cause a denial of service malloc called with the result of an integer-overflowing calculation or possibly have unspecified other impact via a crafted string, as...

Denial Of Service (DoS)

binutils:bionic is vulnerable to Denial Of Service DoS. An issue was discovered in cp-demangle.c in GNU libiberty. There is a stack consumption problem caused by the cplusdemangletype function making recursive calls to itself in certain scenarios involving many 'P' characters...

Denial Of Service (DoS)

binutils is vulnerable to denial of service DoS. An issue was discovered in the Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils 2.32. It is an integer overflow leading to a SEGV in bfddwarf2findnearestline in dwarf2.c, as demonstrated by nm...

Denial Of Service (DoS)

binutils is vulnerable to Denial Of Service DoS. demangletemplate in cplus-dem.c in GNU libiberty allows attackers to trigger excessive memory consumption aka OOM during the "Create an array for saving the template argument values" XNEWVEC call. This can occur during execution of objdump...

Buffer Overflow

binutils:bionic is vulnerable to buffer overflow. An issue was discovered in the Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils through 2.31. There is a heap-based buffer overflow in bfdelf32swapphdrin in elfcode.h because the number of program headers is not...

Denial Of Service (DoS)

binutils:bionic is vulnerable to denial of service DoS. An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils. There is a stack consumption vulnerability resulting from infinite recursion in the functions dname, dencoding, and dlocalname in cp-demangle.c. Remot...

Denial Of Service (DoS)

binutils:bionic is vulnerable to denial of service DoS. An issue was discovered in the Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils. There is a heap-based buffer over-read in bfddoprnt in bfd.c because elfobjectp in elfcode.h mishandles an eshstrndx section of typ...

USN-4516-1 gnupg2 vulnerability

It was discovered that GnuPG signatures could be forged when the SHA-1 algorithm is being used. This update removes validating signatures based on SHA-1 that were generated after 2019-01-19. In environments where this is still required, a new option --allow-weak-key-signatures can be used to reve...

CVE-2020-24979

This CVE ID has been rejected or withdrawn by its CVE Numbering Authority for the following reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: none Mitigation This flaw...

GNU Bash Environment Variable Handling Code Injection (Shellshock)

The remote web server is affected by a command injection vulnerability in GNU Bash known as Shellshock. The vulnerability is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via...
