GLSA-200410-19 : glibc: Insecure tempfile handling in catchsegv script

low Nessus Plugin ID 15538

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200410-19 (glibc: Insecure tempfile handling in catchsegv script)

 The catchsegv script creates temporary files in world-writeable directories with predictable names.
 Impact :

 A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When catchsegv script is called, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user.
 Workaround :

 There is no known workaround at this time.

Solution

All glibc users should upgrade to the latest version:
 # emerge sync # emerge -pv sys-libs/glibc # emerge sys-libs/glibc
