Pure-FTPd 1.0.48 allows remote attackers to prevent legitimate server use by making enough connections to exceed the connection limit.

In Pure-FTPd 1.0.49, a stack exhaustion issue was discovered in the listdir function in ls.c.

Directory traversal vulnerability in pure-FTPd 1.0.22 and possibly other versions, when running on SUSE Linux Enterprise Server and possibly other operating systems, when the Netware OES remote server feature is enabled, allows local users to overwrite arbitrary files via unknown vectors.

Multiple libc/glob(3) flaws were reported [1] that affect various BSD libc implementations. In particular, globs containing braces could lead to resource exhaustion.

One such vulnerable application is Pure-FTPd. This has been corrected in upstream version 1.0.32, where support for braces expansion in directory listings was disabled.

pure-ftpd 1.0.22, as used in SUSE Linux Enterprise Server 10 SP3 and SP4, and Enterprise Desktop 10 SP3 and SP4, when running OES Netware extensions, creates a world-writeable directory, which allows local users to overwrite arbitrary files and gain privileges via unspecified vectors.

Pure-FTPd has released version 1.0.30 which fixes a STARTTLS flaw similar to Postfix's CVE-2011-0411 [1]. Upgrading is recommended.
