CVSS: 7.5EPSS: 17%CPEs: 18EXPL: 0CVE-2019-18679 – squid: Information Disclosure issue in HTTP Digest Authentication
https://notcve.org/view.php?id=CVE-2019-18679
An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to incorrect data management, it is vulnerable to information disclosure when processing HTTP Digest Authentication. Nonce tokens contain the raw byte value of a pointer that sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks. Se descubrió un problema en Squid versiones 2.x, 3.x y versiones 4.x hasta 4.8. • http://www.squid-cache.org/Advisories/SQUID-2019_11.txt http://www.squid-cache.org/Versions/v4/changesets/squid-4-671ba97abe929156dc4c717ee52ad22fba0f7443.patch https://bugzilla.suse.com/show_bug.cgi?id=1156324 https://github.com/squid-cache/squid/pull/491 https://lists.debian.org/debian-lts-announce/2019/12/msg00011.html https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MTM74TU2BSLT5B3H4F3UDW5367 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

SQLite 3.30.1 mishandles pExpr->y.pTab, as demonstrated by the TK_COLUMN case in sqlite3ExprCodeTarget in expr.c. SQLite versión 3.30.1, maneja inapropiadamente pExpr-)y.pTab, como es demostrado por el caso TK_COLUMN en la función sqlite3ExprCodeTarget en el archivo expr.c. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://github.com/sqlite/sqlite/commit/57f7ece78410a8aae86aa4625fb7556897db384c https://usn.ubuntu.com/4205-1 https://www.oracle.com/security-alerts/cpuapr2020.html • CWE-476: NULL Pointer Dereference •

__btrfs_free_extent in fs/btrfs/extent-tree.c in the Linux kernel through 5.3.12 calls btrfs_print_leaf in a certain ENOENT case, which allows local users to obtain potentially sensitive information about register values via the dmesg program. NOTE: The BTRFS development team disputes this issues as not being a vulnerability because “1) The kernel provide facilities to restrict access to dmesg - dmesg_restrict=1 sysctl option. So it's really up to the system administrator to judge whether dmesg access shall be disallowed or not. 2) WARN/WARN_ON are widely used macros in the linux kernel. If this CVE is considered valid this would mean there are literally thousands CVE lurking in the kernel - something which clearly is not the case. ** EN DISPUTA ** __btrfs_free_extent en fs / btrfs / extension-tree.c en el kernel de Linux hasta la versión 5.3.12 llama a btrfs_print_leaf en un caso ENOENT determinado, lo que permite a los usuarios locales obtener información potencialmente confidencial sobre los valores de registro a través del programa dmesg. NOTA: El equipo de desarrollo de BTRFS cuestiona estos problemas por no ser una vulnerabilidad porque “1) El núcleo proporciona facilidades para restringir el acceso a la opción dmesg - dmesg_restrict = 1 sysctl. • https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19039 https://lists.debian.org/debian-lts-announce/2020/12/msg00015.html https://usn.ubuntu.com/4414-1 • CWE-532: Insertion of Sensitive Information into Log File •
CVSS: 6.5EPSS: 0%CPEs: 7EXPL: 1CVE-2019-19221 – libarchive: out-of-bounds read in archive_wstring_append_from_mbs in archive_string.c
https://notcve.org/view.php?id=CVE-2019-19221
In Libarchive 3.4.0, archive_wstring_append_from_mbs in archive_string.c has an out-of-bounds read because of an incorrect mbrtowc or mbtowc call. For example, bsdtar crashes via a crafted archive. En Libarchive versión 3.4.0, la función archive_wstring_append_from_mbs en el archivo archive_string.c presenta una lectura fuera de límites debido a una llamada mbrtowc o mbtowc incorrecta. Por ejemplo, bsdtar se bloquea por medio de un archivo diseñado. • https://github.com/libarchive/libarchive/commit/22b1db9d46654afc6f0c28f90af8cdc84a199f41 https://github.com/libarchive/libarchive/issues/1276 https://lists.debian.org/debian-lts-announce/2022/04/msg00020.html https://lists.debian.org/debian-lts-announce/2022/11/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RHFV25AVTASTWZRF3KTSL357AQ6TYHM4 https://usn.ubuntu.com/4293-1 https://access.redhat.com/security/cve/CVE-2019-19221 https://bugzilla.redhat.com/show • CWE-125: Out-of-bounds Read •
CVSS: 3.3EPSS: 0%CPEs: 7EXPL: 0CVE-2019-19126 – glibc: LD_PREFER_MAP_32BIT_EXEC not ignored in setuid binaries
https://notcve.org/view.php?id=CVE-2019-19126
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. En la arquitectura de x86-64, la Biblioteca GNU C (también se conoce como glibc) versiones anteriores a 2.31 no omite la variable de entorno de LD_PREFER_MAP_32BIT_EXEC durante la ejecución del programa después de una transición de seguridad, permitiendo a atacantes locales restringir las posibles direcciones de mapeo para las bibliotecas cargadas y así omitir ASLR para un programa setuid A vulnerability was discovered in glibc where the LD_PREFER_MAP_32BIT_EXEC environment variable is not ignored when running binaries with the setuid flag on x86_64 architectures. This allows an attacker to force system to utilize only half of the memory (making the system think the software is 32-bit only), thus lowering the amount of memory being used with address space layout randomization (ASLR). The highest threat is confidentiality although the complexity of attack is high. The affected application must already have other vulnerabilities for this flaw to be usable. • https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4FQ5LC6JOYSOYFPRUZ4S45KL6IP3RPPZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZFJ5E7NWOL6ROE5QVICHKIOUGCPFJVUH https://sourceware.org/bugzilla/show_bug.cgi?id=25204 https://usn.ubuntu.com/4416-1 https://access.redhat.com/security/cve/CVE-2019-19126 https://bugzilla.redhat.com/show_bug.cgi?id=1774681 • CWE-20: Improper Input Validation CWE-665: Improper Initialization •
