Hylafax » Hylafax : Security Vulnerabilities, CVEs, CVSS score >= 5

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.

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.

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 entry without a password.

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

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

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

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