Date Id Summary Products Score Patch Annotated
2019-12-11 CVE-2019-14899 A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel. Ipad_os, Iphone_os, Mac_os_x, Tvos, Freebsd, Linux_kernel, Openbsd 7.4
2019-08-26 CVE-2019-8460 OpenBSD kernel version <= 6.5 can be forced to create long chains of TCP SACK holes that causes very expensive calls to tcp_sack_option() for every incoming SACK packet which can lead to a denial of service. Openbsd 7.5
2011-05-09 CVE-2011-1013 Integer signedness error in the drm_modeset_ctl function in (1) drivers/gpu/drm/drm_irq.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.38 and (2) sys/dev/pci/drm/drm_irq.c in the kernel in OpenBSD before 4.9 allows local users to trigger out-of-bounds write operations, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via a crafted num_crtcs (aka vb_num) structure member in an ioctl argument. Linux_kernel, Openbsd N/A
2020-07-28 CVE-2020-16088 iked in OpenIKED, as used in OpenBSD through 6.7, allows authentication bypass because ca.c has the wrong logic for checking whether a public key matches. Openbsd N/A
2020-02-12 CVE-2011-3336 regcomp in the BSD implementation of libc is vulnerable to denial of service due to stack exhaustion. Mac_os_x, Freebsd, Openbsd, Php N/A
2003-03-25 CVE-2003-0028 Integer overflow in the xdrmem_getbytes() function, and possibly other functions, of XDR (external data representation) libraries derived from SunRPC, including libnsl, libc, glibc, and dietlibc, allows remote attackers to execute arbitrary code via certain integer values in length fields, a different vulnerability than CVE-2002-0391. Unicos, Freebsd, Glibc, Hp\-Ux, Hp\-Ux_series_700, Hp\-Ux_series_800, Aix, Kerberos_5, Openafs, Openbsd, Irix, Solaris, Sunos N/A
2001-08-14 CVE-2001-0554 Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function. Freebsd, Aix, Kerberos, Kerberos_5, Netbsd, Linux_netkit, Openbsd, Irix, Solaris, Sunos N/A
2001-06-18 CVE-2001-0247 Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) g_opendir, (2) g_lstat, (3) g_stat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3. Freebsd, Kerberos_5, Netbsd, Openbsd, Irix N/A
2019-12-12 CVE-2019-19726 OpenBSD through 6.6 allows local users to escalate to root because a check for LD_LIBRARY_PATH in setuid programs can be defeated by setting a very small RLIMIT_DATA resource limit. When executing chpass or passwd (which are setuid root), _dl_setup_env in ld.so tries to strip LD_LIBRARY_PATH from the environment, but fails when it cannot allocate memory. Thus, the attacker is able to execute their own library code as root. Openbsd N/A
2019-12-05 CVE-2019-19522 OpenBSD 6.6, in a non-default configuration where S/Key or YubiKey authentication is enabled, allows local users to become root by leveraging membership in the auth group. This occurs because root's file can be written to /etc/skey or /var/db/yubikey, and need not be owned by root. Openbsd N/A
