Hylafax

In HylaFAX Enterprise Web Interface and AvantFAX, the language form element is not properly sanitized before being used and can be misused to include an arbitrary file in the PHP code allowing an attacker to do anything as the web server user. This flaw requires the attacker…

HylaFAX 6.0.6 and HylaFAX+ 5.6.0 allow remote attackers to execute arbitrary code via a dial-in session that provides a FAX page with the JPEG bit enabled, which is mishandled in FaxModem::writeECMData() in the faxd/CopyQuality.c++ file.

sendfax.php in iFAX AvantFAX before 3.3.6 and HylaFAX Enterprise Web Interface before 0.2.5 allows authenticated Command Injection.

HylaFAX+ through 7.0.2 and HylaFAX Enterprise have scripts that execute binaries from directories writable by unprivileged users (e.g., locations under /var/spool/hylafax that are writable by the uucp account). This allows these users to execute code in the context of the user…

In HylaFAX+ through 7.0.2 and HylaFAX Enterprise, the faxsetup utility calls chown on files in user-owned directories. By winning a race, a local attacker could use this to escalate his privileges to root.

Heap-based buffer overflow in hfaxd in HylaFAX+ 5.2.4 through 5.5.3, when using LDAP authentication, might allow remote attackers to cause a denial of service (child hang) or execute arbitrary code via a long USER command.

Multiple eval injection vulnerabilities in HylaFAX 4.2.3 and earlier allow remote attackers to execute arbitrary commands via (1) the notify script in HylaFAX 4.2.0 to 4.2.3 and (2) crafted CallID parameters to the faxrcvd script in HylaFAX 4.2.2 and 4.2.3.

Format string vulnerability in hfaxd for Hylafax 4.1.7 and earlier allows remote attackers to execute arbitrary code.

Hylafax faxsurvey CGI script on Linux allows remote attackers to execute arbitrary commands via shell metacharacters in the query string.

Buffer overflow in faxalter in hylafax 4.0.2 allows local users to gain privileges via a long -m command line argument.

hfaxd in HylaFAX 4.2.3, when PAM support is disabled, accepts arbitrary passwords, which allows remote attackers to gain privileges.

xferfaxstats in HylaFax 4.2.1 and earlier allows local users to overwrite arbitrary files via a symlink attack on the xferfax$$ temporary file.

HylaFax 4.2.1 and earlier does not create or verify ownership of the UNIX domain socket, which might allow local users to read faxes and cause a denial of service by creating the socket using the hyla.unix temporary file.

hfaxd in HylaFAX before 4.2.1, when installed with a "weak" hosts.hfaxd file, allows remote attackers to authenticate and bypass intended access restrictions via a crafted (1) username or (2) hostname that satisfies a regular expression that is matched against a hosts.hfaxd…

Format string vulnerability in HylaFAX faxgetty before 4.1.3 allows remote attackers to cause a denial of service (crash) via the TSI data element.

Buffer overflow in HylaFAX faxgetty before 4.1.3 allows remote attackers to cause a denial of service, and possibly execute arbitrary code, via a long line of image data.

Format string vulnerability in Hylafax on FreeBSD allows local users to execute arbitrary code via format specifiers in the -h hostname argument for (1) faxrm or (2) faxalter.

Format string vulnerability in hfaxd in HylaFAX before 4.1.b2_2 allows local users to gain privileges via the -q command line argument.
