Vulnerabilities

NetBSD prior to commit ec8451e contains a race condition vulnerability in cryptodev_op() within the opencrypto subsystem that allows local attackers to trigger a double-free condition by concurrently issuing CIOCCRYPT op…

NetBSD prior to commit ec8451e contains a signed integer overflow vulnerability in the cryptodev_op() function in sys/opencrypto/cryptodev.c where the local variable iov_len is declared as a signed int but assigned from…

A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd).

ftpd before "NetBSD-ftpd 20230930" can leak information about the host filesystem before authentication via an MLSD or MLST command.

In NetBSD through 9.2, the IPv6 fragment ID generation algorithm employs a weak cryptographic PRNG.

In NetBSD through 9.2, the IPv4 ID generation algorithm does not use appropriate cryptographic measures.

In NetBSD through 9.2, there is an information leak in the TCP ISN (ISS) generation algorithm.

In NetBSD through 9.2, the IPv6 Flow Label generation algorithm employs a weak cryptographic PRNG.

An issue was discovered in the kernel in NetBSD 7.1.

The IPv6 implementation in FreeBSD and NetBSD (unknown versions, year 2012 and earlier) allows remote attackers to cause a denial of service via a flood of ICMPv6 Neighbor Solicitation messages, a different vulnerability…

The IPv6 implementation in FreeBSD and NetBSD (unknown versions, year 2012 and earlier) allows remote attackers to cause a denial of service via a flood of ICMPv6 Router Advertisement packets containing multiple Routing…

Information Disclosure vulnerability in the 802.11 stack, as used in FreeBSD before 8.2 and NetBSD when using certain non-x86 architectures.

The NetBSD qsort() function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort() to deterministically recurse N/4 times.

NetBSD maps the run-time link-editor ld.so directly below the stack region, even if ASLR is enabled, this allows attackers to more easily manipulate memory leading to arbitrary code execution.

A flaw exists in NetBSD's implementation of the stack guard page that allows attackers to bypass it resulting in arbitrary code execution using certain setuid binaries.

mail.local in NetBSD versions 6.0 through 6.0.6, 6.1 through 6.1.5, and 7.0 allows local users to change ownership of or append data to arbitrary files on the target system via a symlink attack on the user mailbox.

CGI handling flaw in bozohttpd in NetBSD 6.0 through 6.0.6, 6.1 through 6.1.5, and 7.0 allows remote attackers to execute arbitrary code via crafted arguments, which are handled by a non-CGI aware program.

The glob implementation in tnftpd (formerly lukemftpd), as used in Apple OS X before 10.11, allows remote attackers to cause a denial of service (memory consumption and daemon outage) via a STAT command containing a craf…

The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource co…

The fetch_url function in usr.bin/ftp/fetch.c in tnftp, as used in NetBSD 5.1 through 5.1.4, 5.2 through 5.2.2, 6.0 through 6.0.6, and 6.1 through 6.1.5 allows remote attackers to execute arbitrary commands via a | (pipe…

The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, a…

The VIQR module in the iconv implementation in FreeBSD 10.0 before p6 and NetBSD allows context-dependent attackers to cause a denial of service (out-of-bounds array access) via a crafted argument to the iconv_open funct…

The HZ module in the iconv implementation in FreeBSD 10.0 before p6 and NetBSD allows context-dependent attackers to cause a denial of service (NULL pointer dereference) via a crafted argument to the iconv_open function.

bozotic HTTP server (aka bozohttpd) before 20140708, as used in NetBSD, truncates paths when checking .htpasswd restrictions, which allows remote attackers to bypass the HTTP authentication scheme and access restrictions…

The ipalloc function in libc/stdlib/malloc.c in jemalloc in libc for FreeBSD 6.4 and NetBSD does not properly allocate memory, which makes it easier for context-dependent attackers to perform memory-related attacks such…
