Vulnerabilidades

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.

GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate.

libaspell.a in GNU Aspell before 0.60.8 has a buffer over-read for a string ending with a single '\0' byte, if the encoding is set to ucs-2 or ucs-4 outside of the application, as demonstrated by the ASPELL_CONF environment variable.

Integer overflow in the keycompare_mb function in sort.c in sort in GNU Coreutils through 8.23 might allow attackers to cause a denial of service (application crash) or possibly have unspecified other impact via long strings.

The keycompare_mb function in sort.c in sort in GNU Coreutils through 8.23 on 64-bit platforms performs a size calculation without considering the number of bytes occupied by multibyte characters, which allows attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have…

UNIX Symbolic Link (Symlink) Following vulnerability in the packaging of gnump3d in openSUSE Leap 15.1 allows local attackers to escalate from user gnump3d to root. This issue affects: openSUSE Leap 15.1 gnump3d version 3.0-lp151.2.1 and prior versions.

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).

GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in bfr_read in decode.c.

GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in bit_search_sentinel in bits.c.

GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in copy_compressed_bytes in decode_r2007.c.

GNU LibreDWG 0.9.3.2564 has a NULL pointer dereference in get_next_owned_entity in dwg.c.

GNU LibreDWG 0.9.3.2564 has an attempted excessive memory allocation in read_sections_map in decode_r2007.c.

GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in read_pages_map in decode_r2007.c.

In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives. When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting…

An issue was discovered in GNU LibreDWG 0.92. Crafted input will lead to an attempted excessive memory allocation in dwg_decode_LWPOLYLINE_private in dwg.spec.

An issue was discovered in GNU LibreDWG before 0.93. There is a double-free in dwg_free in free.c.

An issue was discovered in GNU LibreDWG before 0.93. Crafted input will lead to an attempted excessive memory allocation in decode_3dsolid in dwg.spec.

An issue was discovered in GNU LibreDWG 0.92. Crafted input will lead to an attempted excessive memory allocation in dwg_decode_HATCH_private in dwg.spec.

An issue was discovered in GNU LibreDWG 0.92. There is a heap-based buffer over-read in decode_R13_R2000 in decode.c.

An issue was discovered in GNU LibreDWG 0.92. There is a use-after-free in resolve_objectref_vector in decode.c.

An issue was discovered in GNU LibreDWG before 0.93. Crafted input will lead to an attempted excessive memory allocation in dwg_decode_SPLINE_private in dwg.spec.

GnuTLS incorrectly validates the first byte of padding in CBC modes

The mpi_powm function in Libgcrypt before 1.6.3 and GnuPG before 1.4.19 allows attackers to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a "Last-Level Cache Side-Channel Attack."

Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate attackers to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the electromagnetic field during multiplication.

A flaw was found in the grub2-set-bootflag utility of grub2. A local attacker could run this utility under resource pressure (for example by setting RLIMIT), causing grub2 configuration files to be truncated and leaving the system unbootable on subsequent reboots.
