CVSS: 7.8EPSS: 12%CPEs: 59EXPL: 31CVE-2022-0847 – Linux Kernel Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-0847
A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system. Se ha encontrado un fallo en la forma en que el miembro "flags" de la estructura del nuevo búfer de la tubería carecía de la inicialización apropiada en las funciones copy_page_to_iter_pipe y push_pipe en el kernel de Linux y, por tanto, podía contener valores obsoletos. Un usuario local no privilegiado podía usar este fallo para escribir en páginas de la caché de páginas respaldadas por archivos de sólo lectura y así escalar sus privilegios en el sistema Linux versions 4.20 and above have an issue where ktls writes into spliced readonly pages. Linux kernel contains an improper initialization vulnerability where an unprivileged local user could escalate their privileges on the system. • https://www.exploit-db.com/exploits/50808 https://github.com/Arinerron/CVE-2022-0847-DirtyPipe-Exploit https://github.com/AlexisAhmed/CVE-2022-0847-DirtyPipe-Exploits https://github.com/r1is/CVE-2022-0847 https://github.com/bbaranoff/CVE-2022-0847 https://github.com/Al1ex/CVE-2022-0847 https://github.com/antx-code/CVE-2022-0847 https://github.com/basharkey/CVE-2022-0847-dirty-pipe-checker https://github.com/knqyf263/CVE-2022-0847 https://github.com/chenaotian/CVE-2022- • CWE-665: Improper Initialization CWE-909: Missing Initialization of Resource •

In nbd-server in nbd before 3.24, there is an integer overflow with a resultant heap-based buffer overflow. A value of 0xffffffff in the name length field will cause a zero-sized buffer to be allocated for the name, resulting in a write to a dangling pointer. This issue exists for the NBD_OPT_INFO, NBD_OPT_GO, and NBD_OPT_EXPORT_NAME messages. En nbd-server en nbd versiones anteriores a 3.24, se presenta un desbordamiento de enteros con un desbordamiento de búfer en la región heap de la memoria resultante. Un valor de 0xffffff en el campo de longitud del nombre causará que se asigne un búfer de tamaño cero para el nombre, resultando en una escritura en un puntero colgante. • https://lists.debian.org/debian-lts-announce/2022/03/msg00014.html https://lists.debian.org/nbd/2022/01/msg00037.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/G2UPX62BIWOOHSACGUDB7E3O4URNN37F https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IZHR73XMAJTCFGKUZRXVTZKCK2X3IFNA https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PU5JFD4PEJED72TZLZ5R2Q2SFXICU5I5 https://security.gentoo.org/glsa/202402-10 • CWE-190: Integer Overflow or Wraparound •
CVSS: 9.8EPSS: 0%CPEs: 6EXPL: 1CVE-2022-26496 – Shannon Baseband fmtp SDP Attribute Memory Corruption
https://notcve.org/view.php?id=CVE-2022-26496
In nbd-server in nbd before 3.24, there is a stack-based buffer overflow. An attacker can cause a buffer overflow in the parsing of the name field by sending a crafted NBD_OPT_INFO or NBD_OPT_GO message with an large value as the length of the name. En nbd-server en nbd versiones anteriores a 3.24, se presenta un desbordamiento del búfer en la región stack de la memoria. Un atacante puede causar un desbordamiento de búfer en el análisis del campo name enviando un mensaje NBD_OPT_INFO o NBD_OPT_GO diseñado con un valor grande como longitud del nombre Shannon Baseband suffers from a memory corruption vulnerability that occurs when the baseband modem processes SDP when setting up a call. When an fmtp attribute is parsed, the integer that represents the payload type is copied into an 8-byte buffer using memcpy with the length of payload type as the length parameter. • http://packetstormsecurity.com/files/172148/Shannon-Baseband-fmtp-SDP-Attribute-Memory-Corruption.html https://lists.debian.org/nbd/2022/01/msg00036.html https://lists.debian.org/nbd/2022/01/msg00037.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/G2UPX62BIWOOHSACGUDB7E3O4URNN37F https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IZHR73XMAJTCFGKUZRXVTZKCK2X3IFNA https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject • CWE-787: Out-of-bounds Write •
CVSS: 9.8EPSS: 8%CPEs: 5EXPL: 1CVE-2022-24724 – Integer overflow in table parsing extension leads to heap memory corruption
https://notcve.org/view.php?id=CVE-2022-24724
cmark-gfm is GitHub's extended version of the C reference implementation of CommonMark. Prior to versions 0.29.0.gfm.3 and 0.28.3.gfm.21, an integer overflow in cmark-gfm's table row parsing `table.c:row_from_string` may lead to heap memory corruption when parsing tables who's marker rows contain more than UINT16_MAX columns. The impact of this heap corruption ranges from Information Leak to Arbitrary Code Execution depending on how and where `cmark-gfm` is used. If `cmark-gfm` is used for rendering remote user controlled markdown, this vulnerability may lead to Remote Code Execution (RCE) in applications employing affected versions of the `cmark-gfm` library. This vulnerability has been patched in the following cmark-gfm versions 0.29.0.gfm.3 and 0.28.3.gfm.21. • http://packetstormsecurity.com/files/166599/cmark-gfm-Integer-overflow.html https://github.com/github/cmark-gfm/security/advisories/GHSA-mc3g-88wq-6f4x https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5CYUU662VO6CCXQKVZVOHXX3RGIF2DLQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F7V3HAM5H6YFJG2QFEXACZR3XVWFTXTC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KH4UQA6VWVZU5EW3HNEAB7D7BTCNJSJ2 https://lists.fedorapro • CWE-190: Integer Overflow or Wraparound •
