Integer overflow in the getword function in options.c in pppd in Paul's PPP Package (ppp) before 2.4.7 allows attackers to "access privileged options" via a long word in an options file, which triggers a heap-based buffer overflow that "[corrupts] security-relevant variables."

According to the versions of the ppp package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Integer overflow in the getword function in options.c     in pppd in Paul's PPP Package (ppp) before 2.4.7 allows     attackers to 'access privileged options' via a long     word in an options file, which triggers a heap-based     buffer overflow that 'corrupts security-relevant     variables.'(CVE-2014-3158)

  - Buffer overflow in the rc_mksid function in     plugins/radius/util.c in Paul's PPP Package (ppp) 2.4.6     and earlier, when the PID for pppd is greater than     65535, allows remote attackers to cause a denial of     service (crash) via a start accounting message to the     RADIUS server.(CVE-2015-3310)

  - eap.c in pppd in ppp 2.4.2 through 2.4.8 has an     rhostname buffer overflow in the eap_request and     eap_response functions.(CVE-2020-8597)

New ppp packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, and -current to fix security issues.

Updated ppp packages fix security vulnerability :

A vulnerability in ppp before 2.4.7 may enable an unprivileged attacker to access privileged options (CVE-2014-3158).

This updates fixes a potential integer overflow in option parsing.

A user in the group 'dip' could provide a specially crafted configuration file of more than 2G and generate an integer overflow.
This may enable an attacker to overwrite the heap and thereby corrupt security-relevant variables.

The remote host is affected by the vulnerability described in GLSA-201412-19 (PPP: Information disclosure)

    Integer overflow is discovered in the getword function in options.c in       PPP   Impact :

    A local attacker could execute process with extremely long options list,       possibly obtaining sensitive information.
  Workaround :

    There is no known workaround at this time.

It was discovered that ppp incorrectly handled certain options files.
A local attacker could possibly use this issue to escalate privileges.

A vulnerability was discovered in ppp, an implementation of the Point-to-Point Protocol: an integer overflow in the routine responsible for parsing user-supplied options potentially allows a local attacker to gain root privileges.

ppp was updated to fix an integer overflow in option parsing.
(CVE-2014-3158, bnc#891489).

This ppp update fixes a potential security issue that an unprivileged attacker could access privileged options :

  - integer overflow in option parsing (CVE-2014-3158,     bnc#891489)

Security fix for CVE-2014-3158
