Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-468-1)
Summary:	The remote host is missing an update for the Debian 'libuser' package(s) announced via the DLA-468-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'libuser' package(s) announced via the DLA-468-1 advisory. Vulnerability Insight: Two security vulnerabilities were discovered in libuser, a library that implements a standardized interface for manipulating and administering user and group accounts, that could lead to a denial of service or privilege escalation by local users. CVE-2015-3245 Incomplete blacklist vulnerability in the chfn function in libuser before 0.56.13-8 and 0.60 before 0.60-7, as used in the userhelper program in the usermode package, allows local users to cause a denial of service (/etc/passwd corruption) via a newline character in the GECOS field. CVE-2015-3246 libuser before 0.56.13-8 and 0.60 before 0.60-7, as used in the userhelper program in the usermode package, directly modifies /etc/passwd, which allows local users to cause a denial of service (inconsistent file state) by causing an error during the modification. NOTE: this issue can be combined with CVE-2015-3245 to gain privileges. In addition the usermode package, which depends on libuser, was rebuilt against the updated version. For Debian 7 Wheezy, these problems have been fixed in libuser 1:0.56.9.dfsg.1-1.2+deb7u1 usermode 1.109-1+deb7u2 We recommend that you upgrade your libuser and usermode packages. Affected Software/OS: 'libuser' package(s) on Debian 7. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
