CVE-2019-19012 [CRITICAL] CWE-125 CVE-2019-19012: An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 l An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 leads to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (This only affects the 32-bit compiled version). Remote attackers can cause a denial-of-service or information disclosure, or possibly have unspecif

CVE-2013-0221 [MEDIUM] CWE-20 CVE-2013-0221: The SUSE coreutils-i18n.patch for GNU coreutils allows context-dependent attackers to cause a denial The SUSE coreutils-i18n.patch for GNU coreutils allows context-dependent attackers to cause a denial of service (segmentation fault and crash) via a long string to the sort command, when using the (1) -d or (2) -M switch, which triggers a stack-based buffer overflow in the alloca function.

CVE-2019-19340 [HIGH] CWE-1188 CVE-2019-19340: A flaw was found in Ansible Tower, versions 3.6.x before 3.6.2 and 3.5.x before 3.5.3, where enablin A flaw was found in Ansible Tower, versions 3.6.x before 3.6.2 and 3.5.x before 3.5.3, where enabling RabbitMQ manager by setting it with '-e rabbitmq_enable_manager=true' exposes the RabbitMQ management interface publicly, as expected. If the default admin user is still active, an attacker could guess the password and gain access to the system.

CVE-2026-102559 [HIGH] CWE-125 CVE-2026-102559: A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outg A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow.

CVE-2026-102558 [HIGH] CWE-125 CVE-2026-102558: A flaw was found in libsoup. When max-incoming-payload-size is unlimited (0), SoupWebsocketConnectio A flaw was found in libsoup. When max-incoming-payload-size is unlimited (0), SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data.

CVE-2019-6470 [HIGH] CVE-2019-6470: There had existed in one of the ISC BIND libraries a bug in a function that was used by dhcpd when o There had existed in one of the ISC BIND libraries a bug in a function that was used by dhcpd when operating in DHCPv6 mode. There was also a bug in dhcpd relating to the use of this function per its documentation, but the bug in the library function prevented this from causing any harm. All releases of dhcpd from ISC contain copies of this, and other, BIND lib

CVE-2026-35091 [HIGH] CWE-253 CVE-2026-35091: A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vul A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol (UDP) packet. This can lead to an out-of-bounds read, causing a denial of service (DoS) and potentially disclosing limited memory conte

CVE-2026-3497 [HIGH] CWE-908 CVE-2026-3497: Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerabilit Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI

CVE-2019-10196 [CRITICAL] CWE-665 CVE-2019-10196: A flaw was found in http-proxy-agent, prior to version 2.1.0. It was discovered http-proxy-agent pas A flaw was found in http-proxy-agent, prior to version 2.1.0. It was discovered http-proxy-agent passes an auth option to the Buffer constructor without proper sanitization. This could result in a Denial of Service through the usage of all available CPU resources and data exposure through an uninitialized memory leak in setups where an attacker co

CVE-2026-50259 [HIGH] CWE-121 CVE-2026-50259: A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. _XkbSetMapChecks() A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. _XkbSetMapChecks() declares a fixed-size stack buffer mapWidths[256] indexed by key type index. The helper function CheckKeyTypes() writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This may be used to crash the server, or for privilege

CVE-2026-50256 [HIGH] CWE-121 CVE-2026-50256: A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias target name length is 1024 bytes. A font alias name betwe

CVE-2026-9064 [HIGH] CWE-770 CVE-2026-9064: A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls within the default maximum BER message size (2 MB), c

CVE-2021-4048 [CRITICAL] CWE-125 CVE-2021-4048: An out-of-bounds read flaw was found in the CLARRV, DLARRV, SLARRV, and ZLARRV functions in lapack t An out-of-bounds read flaw was found in the CLARRV, DLARRV, SLARRV, and ZLARRV functions in lapack through version 3.10.0, as also used in OpenBLAS before version 0.3.18. Specially crafted inputs passed to these functions could cause an application using lapack to crash or possibly disclose portions of its memory.

CVE-2026-3833 [HIGH] CWE-178 CVE-2026-3833: A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive compari A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subje

CVE-2023-2156 [HIGH] CWE-617 CVE-2023-2156: A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL prot A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the system.

CVE-2013-3301 [HIGH] CVE-2013-3301: The ftrace implementation in the Linux kernel before 3.8.8 allows local users to cause a denial of s The ftrace implementation in the Linux kernel before 3.8.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for write access to the (1) set_ftrace_pid or (2) set_graph_function file, and then making an lseek system call.

CVE-2004-1235 [MEDIUM] CVE-2004-1235: Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux ke Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.
