Buffer overflow in the decode_post function in ELOG before 2.5.7 allows remote attackers to execute arbitrary code via attachments with long file names.

ELOG before 2.5.7 allows remote attackers to bypass authentication and download a configuration file that contains a sensitive write password via a modified URL.

Directory traversal vulnerability in ELOG before 2.6.1 allows remote attackers to access arbitrary files outside of the elog directory via "../" (dot dot) sequences in the URL.

Format string vulnerability in the write_logfile function in ELOG before 2.6.1 allows remote attackers to cause a denial of service (server crash) via unknown attack vectors. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Multiple stack-based buffer overflows in elogd.c in elog before 2.5.7 r1558-4 allow attackers to cause a denial of service (application crash) and possibly execute code via long "revision attributes".

Buffer overflow in elogd.c in elog before 2.5.7 r1558-4 allows attackers to execute code via unspecified variables, when writing to the log file.

The (1) elog.c and (2) elogd.c components in elog before 2.5.7 r1558-4 generate different responses depending on whether or not a username is valid, which allows remote attackers to determine valid usernames.

elog before 2.5.7 r1558-4 allows remote attackers to cause a denial of service (infinite redirection) via a request with the fail parameter set to 1, which redirects to the same request.
