CVE-2017-5390 [CRITICAL] CVE-2017-5390: The JSON viewer in the Developer Tools uses insecure methods to create a communication channel for c The JSON viewer in the Developer Tools uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.

CVE-2017-3071 [HIGH] CWE-416 CVE-2017-3071: Adobe Flash Player versions 25.0.0.148 and earlier have an exploitable use after free vulnerability Adobe Flash Player versions 25.0.0.148 and earlier have an exploitable use after free vulnerability when masking display objects. Successful exploitation could lead to arbitrary code execution.

CVE-2026-58014 [HIGH] CWE-193 CVE-2026-58014: A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list fun A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary.

CVE-2021-20305 [HIGH] CWE-327 CVE-2021-20305: A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification fun A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions (GOST DSA, EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an invalid signature, causing

CVE-2011-3188 [CRITICAL] CVE-2011-3188: The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorith The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets.

CVE-2026-102556 [HIGH] CWE-843 CVE-2026-102556: A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection emitted the ::pong signal with a GByteArray pointer even though the signal is declared to pass a GBytes. Applications connecting a handler that follows the documented GBytes API can trigger heap corruption or a crash upon receiving a crafted Pong.

CVE-2026-0966 [HIGH] CWE-124 CVE-2026-0966: A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service w A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the server's logging verbosity is set to `SSH_LOG_PACKET (3)` or higher. Successful ex

CVE-2017-3074 [HIGH] CWE-787 CVE-2017-3074: Adobe Flash Player versions 25.0.0.148 and earlier have an exploitable memory corruption vulnerabili Adobe Flash Player versions 25.0.0.148 and earlier have an exploitable memory corruption vulnerability in the Graphics class. Successful exploitation could lead to arbitrary code execution.

CVE-2019-19906 [HIGH] CWE-193 CVE-2019-19906: cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote deni cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl.

CVE-2012-1149 [HIGH] CWE-189 CVE-2012-1149: Integer overflow in the vclmi.dll module in OpenOffice.org (OOo) 3.3, 3.4 Beta, and possibly earlier Integer overflow in the vclmi.dll module in OpenOffice.org (OOo) 3.3, 3.4 Beta, and possibly earlier, and LibreOffice before 3.5.3, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted embedded image object, as demonstrated by a JPEG image in a .DOC file, which triggers a heap-based b

CVE-2004-0882 [CRITICAL] CVE-2004-0882: Buffer overflow in the QFILEPATHINFO request handler in Samba 3.0.x through 3.0.7 may allow remote a Buffer overflow in the QFILEPATHINFO request handler in Samba 3.0.x through 3.0.7 may allow remote attackers to execute arbitrary code via a TRANSACT2_QFILEPATHINFO request with a small "maximum data bytes" value.

CVE-2026-42009 [HIGH] CWE-475 CVE-2026-42009: A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined beha

CVE-2013-4342 [HIGH] CWE-264 CVE-2013-4342: xinetd does not enforce the user and group configuration directives for TCPMUX services, which cause xinetd does not enforce the user and group configuration directives for TCPMUX services, which causes these services to be run as root and makes it easier for remote attackers to gain privileges by leveraging another vulnerability in a service.

CVE-2026-19654 [HIGH] CWE-125 CVE-2026-19654: A unauthenticated remote peer may lead rsyslogd to crash due to a flaw in the optional imptcp module A unauthenticated remote peer may lead rsyslogd to crash due to a flaw in the optional imptcp module. A crafted input sequence during oversize-frame recovery can cause an invalid internal message length and terminate rsyslogd. No confidentiality or integrity impact, privilege escalation, or code execution has been identified. imtcp and the default imp

CVE-2026-73197 [HIGH] CWE-770 CVE-2026-73197: A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by se A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potentia

CVE-2019-8324 [HIGH] CWE-94 CVE-2019-8324: An issue was discovered in RubyGems 2.6 and later through 3.0.2. A crafted gem with a multi-line nam An issue was discovered in RubyGems 2.6 and later through 3.0.2. A crafted gem with a multi-line name is not handled correctly. Therefore, an attacker could inject arbitrary code to the stub line of gemspec, which is eval-ed by code in ensure_loadable_spec during the preinstall check.

CVE-2022-27666 [HIGH] CWE-787 CVE-2022-27666: A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ip A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.

CVE-2026-53006 [CRITICAL] CWE-416 CVE-2026-53006: In the Linux kernel, the following vulnerability has been resolved: ipv6: fix possible UAF in icmpv In the Linux kernel, the following vulnerability has been resolved: ipv6: fix possible UAF in icmpv6_rcv() Caching saddr and daddr before pskb_pull() is problematic since skb->head can change. Remove these temporary variables: - We only access &ipv6_hdr(skb)->saddr and &ipv6_hdr(skb)->daddr when net_dbg_ratelimited() is called in the slow path.

CVE-2020-10696 [HIGH] CWE-22 CVE-2020-10696: A path traversal flaw was found in Buildah in versions before 1.14.5. This flaw allows an attacker t A path traversal flaw was found in Buildah in versions before 1.14.5. This flaw allows an attacker to trick a user into building a malicious container image hosted on an HTTP(s) server and then write files to the user's system anywhere that the user has permissions.
