Vulnerability Assessment Details

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

Vulnerability Assessment Summary
glibc: Insecure tempfile handling in catchsegv script

Detailed Explanation for this Vulnerability Assessment
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.
