mod_proxy_http.c in mod_proxy_http in the Apache HTTP Server 2.2.9 through 2.2.15, 2.3.4-alpha, and 2.3.5-alpha on Windows, NetWare, and OS/2, in certain configurations involving proxy worker pools, does not properly detect timeouts, which allows remote attackers to obtain a potentially sensitive response intended for a different client in opportunistic circumstances via a normal HTTP request.

NWFTPD.nlm before 5.08.06 in the FTP server in Novell NetWare does not properly handle partial matches for container names in the FTPREST.TXT file, which allows remote attackers to bypass intended access restrictions via an FTP session.

NWFTPD.nlm before 5.06.04 in the FTP server in Novell NetWare allows remote attackers to cause a denial of service (excessive stale connections) by establishing many FTP sessions, which persist in the Not-Logged-In state after each session is completed.

NWFTPD.nlm before 5.04.25 in the FTP server in Novell NetWare does not promptly close DS sessions, which allows remote attackers to cause a denial of service (connection slot exhaustion) by establishing many FTP sessions that persist for the lifetime of a DS session.

Unspecified vulnerability in NWFTPD.nlm before 5.03b in the FTP server in Novell NetWare allows remote attackers to cause a denial of service (abend) via a crafted username.

NWFTPD.nlm before 5.01w in the FTP server in Novell NetWare allows remote attackers to cause a denial of service (abend) via an anonymous STOU command.

Unspecified vulnerability in the dpwinsup module (dpwinsup.dll) for dpwingad (dpwingad.exe) in HP Data Protector Express and Express SSE 3.x before build 47065, and Express and Express SSE 4.x before build 46537, allows remote attackers to cause a denial of service (application crash) or read portions of memory via one or more crafted packets.

The Novell Netware client running on Windows 95 allows local users to bypass the login and open arbitrary files via the "What is this?" help feature, which can be launched from the Novell Netware login screen.

Novell NetWare Transaction Tracking System (TTS) in Novell 4.11 and earlier allows remote attackers to cause a denial of service via a large number of requests.

NetWare NFS mode 1 and 2 implements the "Read Only" flag in Unix by changing the ownership of a file to root, which allows local users to gain root privileges by creating a setuid program and setting it to "Read Only," which NetWare-NFS changes to a setuid root program.

Novell 5 and earlier, when running over IPX with a packet signature level less than 3, allows remote attackers to gain administrator privileges by spoofing the MAC address in IPC fragmented packets that make NetWare Core Protocol (NCP) calls.

Novell NetWare with Novell-HTTP-Server or YAWN web servers allows remote attackers to conduct a denial of service via a large number of HTTP GET requests.

The installation of Novell Netware NDS 5.99 provides an unauthenticated client with Read access for the tree, which allows remote attackers to access sensitive information such as users, groups, and readable objects via CX.EXE and NLIST.EXE.
