1 CVE-2020-25717 20 2022-02-18 2022-02-25
8.5
 None Remote Low ??? Complete Complete None
A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.
2 CVE-2019-17666 120 Overflow 2019-10-17 2023-01-19
8.3
 None Local Network Low Not required Complete Complete Complete
rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow.
3 CVE-2019-3846 122 2019-06-03 2023-02-12
8.3
 None Local Network Low Not required Complete Complete Complete
A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network.
4 CVE-2018-19518 88 Exec Code 2018-11-25 2022-04-18
8.5
 None Remote Medium ??? Complete Complete Complete
University of Washington IMAP Toolkit 2007f on UNIX, as used in imap_open() in PHP and other products, launches an rsh command (by means of the imap_rimap function in c-client/imap4r1.c and the tcp_aopen function in osdep/unix/tcp_unix.c) without preventing argument injection, which might allow remote attackers to execute arbitrary OS commands if the IMAP server name is untrusted input (e.g., entered by a user of a web application) and if rsh has been replaced by a program with different argument semantics. For example, if rsh is a link to ssh (as seen on Debian and Ubuntu systems), then the attack can use an IMAP server name containing a "-oProxyCommand" argument.
5 CVE-2018-14633 121 Overflow 2018-09-25 2023-02-14
8.3
 None Remote Medium Not required Partial Partial Complete
A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable.
6 CVE-2015-4004 119 DoS Overflow +Info 2015-06-07 2022-12-12
8.5
 None Remote Low Not required Partial None Complete
The OZWPAN driver in the Linux kernel through 4.0.5 relies on an untrusted length field during packet parsing, which allows remote attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read and system crash) via a crafted packet.
7 CVE-2015-1803 DoS Exec Code 2015-03-20 2016-12-31
8.5
 None Remote Medium ??? Complete Complete Complete
The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly handle character bitmaps it cannot read, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) and possibly execute arbitrary code via a crafted BDF font file.
8 CVE-2013-1900 189 2013-04-04 2017-10-20
8.5
 None Remote Medium ??? Complete Complete Complete
PostgreSQL 9.2.x before 9.2.4, 9.1.x before 9.1.9, 9.0.x before 9.0.13, and 8.4.x before 8.4.17, when using OpenSSL, generates insufficiently random numbers, which might allow remote authenticated users to have an unspecified impact via vectors related to the "contrib/pgcrypto functions."
9 CVE-2010-3705 400 DoS Mem. Corr. 2010-11-26 2023-02-13
8.3
 None Local Network Low Not required Complete Complete Complete
The sctp_auth_asoc_get_hmac function in net/sctp/auth.c in the Linux kernel before 2.6.36 does not properly validate the hmac_ids array of an SCTP peer, which allows remote attackers to cause a denial of service (memory corruption and panic) via a crafted value in the last element of this array.
10 CVE-2007-2443 Exec Code 2007-06-26 2021-02-02
8.3
 None Local Network Low Not required Complete Complete Complete
Integer signedness error in the gssrpc__svcauth_unix function in svc_auth_unix.c in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a negative length value.
