CVE-2009-0846 5 Apple, Canonical, Fedoraproject and 2 more 9 Mac Os X, Ubuntu Linux, Fedora and 6 more 2024-02-09 10.0 HIGH N/A
The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.
CVE-2008-4989 6 Canonical, Debian, Fedoraproject and 3 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-02-09 4.3 MEDIUM 5.9 MEDIUM
The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN).
CVE-2012-5821 2 Canonical, Lynx 2 Ubuntu Linux, Lynx 2024-02-09 5.8 MEDIUM 5.9 MEDIUM
Lynx does not verify that the server's certificate is signed by a trusted certification authority, which allows man-in-the-middle attackers to spoof SSL servers via a crafted certificate, related to improper use of a certain GnuTLS function.
CVE-2005-2946 2 Canonical, Openssl 2 Ubuntu Linux, Openssl 2024-02-09 5.0 MEDIUM 7.5 HIGH
The default configuration on OpenSSL before 0.9.8 uses MD5 for creating message digests instead of a more cryptographically strong algorithm, which makes it easier for remote attackers to forge certificates with a valid certificate authority signature.
CVE-2008-0062 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-02-09 9.3 HIGH 9.8 CRITICAL
KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free.
CVE-2008-0063 7 Apple, Canonical, Debian and 4 more 11 Mac Os X, Mac Os X Server, Ubuntu Linux and 8 more 2024-02-09 4.3 MEDIUM 7.5 HIGH
The Kerberos 4 support in KDC in MIT Kerberos 5 (krb5kdc) does not properly clear the unused portion of a buffer when generating an error message, which might allow remote attackers to obtain sensitive information, aka "Uninitialized stack values."
CVE-2009-3620 6 Canonical, Fedoraproject, Linux and 3 more 8 Ubuntu Linux, Fedora, Linux Kernel and 5 more 2024-02-09 4.9 MEDIUM 7.8 HIGH
The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls.
CVE-2009-0949 5 Apple, Canonical, Debian and 2 more 7 Cups, Mac Os X, Mac Os X Server and 4 more 2024-02-09 5.0 MEDIUM 7.5 HIGH
The ippReadIO function in cups/ipp.c in cupsd in CUPS before 1.3.10 does not properly initialize memory for IPP request packets, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a scheduler request with two consecutive IPP_TAG_UNSUPPORTED tags.
CVE-2008-2934 3 Apple, Canonical, Mozilla 3 Mac Os X, Ubuntu Linux, Firefox 2024-02-08 6.8 MEDIUM 8.8 HIGH
Mozilla Firefox 3 before 3.0.1 on Mac OS X allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted GIF file that triggers a free of an uninitialized pointer.
CVE-2005-1513 3 Canonical, Debian, Qmail Project 3 Ubuntu Linux, Debian Linux, Qmail 2024-02-08 5.0 MEDIUM 9.8 CRITICAL
Integer overflow in the stralloc_readyplus function in qmail, when running on 64 bit platforms with a large amount of virtual memory, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large SMTP request.
CVE-2020-15708 1 Canonical 1 Ubuntu Linux 2024-02-08 4.6 MEDIUM 7.8 HIGH
Ubuntu's packaging of libvirt in 20.04 LTS created a control socket with world read and write permissions. An attacker could use this to overwrite arbitrary files or execute arbitrary code.
CVE-2004-1002 2 Canonical, Samba 2 Ubuntu Linux, Ppp 2024-02-08 5.0 MEDIUM 7.5 HIGH
Integer underflow in pppd in cbcp.c for ppp 2.4.1 allows remote attackers to cause a denial of service (daemon crash) via a CBCP packet with an invalid length value that causes pppd to access an incorrect memory location.
CVE-2006-6811 2 Canonical, Kde 2 Ubuntu Linux, Ksirc 2024-02-08 4.3 MEDIUM 6.5 MEDIUM
KsIRC 1.3.12 allows remote attackers to cause a denial of service (crash) via a long PRIVMSG string when connecting to an Internet Relay Chat (IRC) server, which causes an assertion failure and results in a NULL pointer dereference. NOTE: this issue was originally reported as a buffer overflow.
CVE-2006-5779 2 Canonical, Openldap 2 Ubuntu Linux, Openldap 2024-02-08 5.0 MEDIUM 7.5 HIGH
OpenLDAP before 2.3.29 allows remote attackers to cause a denial of service (daemon crash) via LDAP BIND requests with long authcid names, which triggers an assertion failure.
CVE-2017-15129 4 Canonical, Fedoraproject, Linux and 1 more 20 Ubuntu Linux, Fedora, Linux Kernel and 17 more 2024-02-08 4.9 MEDIUM 4.7 MEDIUM
A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.
CVE-2009-1386 3 Canonical, Openssl, Redhat 3 Ubuntu Linux, Openssl, Openssl 2024-02-07 5.0 MEDIUM N/A
ssl/s3_pkt.c in OpenSSL before 0.9.8i allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a DTLS ChangeCipherSpec packet that occurs before ClientHello.
CVE-2009-1378 2 Canonical, Openssl 2 Ubuntu Linux, Openssl 2024-02-07 5.0 MEDIUM N/A
Multiple memory leaks in the dtls1_process_out_of_seq_message function in ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allow remote attackers to cause a denial of service (memory consumption) via DTLS records that (1) are duplicates or (2) have sequence numbers much greater than current sequence numbers, aka "DTLS fragment handling memory leak."
CVE-2009-1387 3 Canonical, Openssl, Redhat 3 Ubuntu Linux, Openssl, Openssl 2024-02-07 5.0 MEDIUM N/A
The dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL before 1.0.0 Beta 2 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence DTLS handshake message, related to a "fragment bug."
CVE-2019-15118 5 Canonical, Debian, Linux and 2 more 12 Ubuntu Linux, Debian Linux, Linux Kernel and 9 more 2024-02-03 4.9 MEDIUM 5.5 MEDIUM
check_input_term in sound/usb/mixer.c in the Linux kernel through 5.2.9 mishandles recursion, leading to kernel stack exhaustion.
CVE-2010-0050 4 Apple, Canonical, Fedoraproject and 1 more 5 Iphone Os, Safari, Ubuntu Linux and 2 more 2024-02-03 9.3 HIGH 8.8 HIGH
Use-after-free vulnerability in WebKit in Apple Safari before 4.0.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via an HTML document with improperly nested tags.
