sos: Usage of predictable temporary files allows privilege escalation
sosreport in SoS 3.x allows local users to obtain sensitive information from sosreport files or gain privileges via a symlink attack on an archive file in a temporary directory, as demonstrated by sosreport-$hostname-$date.tar in /tmp/sosreport-$hostname-$date.
An insecure temporary file use flaw was found in the way sos created certain sosreport files. A local attacker could possibly use this flaw to perform a symbolic link attack to reveal the contents of sosreport files, or in some cases modify arbitrary files and escalate their privileges on the system.

CVE-2015-7529 [HIGH] CVE-2015-7529 sos: Usage of predictable temporary files allows privilege escalation
CVE-2015-7529 sos: Usage of predictable temporary files allows privilege escalation
A vulnerability in sosreport was reported, allowing a privilege escalation to unprivileged attacker on RHEL-6, and change the owner and content of certain files on RHEL-7.
sosreport creates temporary directory in /tmp with predictable name sosreport-$hostname-$date with permissions set to 700. Then it creates a tar file with the aforementioned name + .tar suffix. Further it invokes open() with no O_NOFOLLOW nor O_EXCL set, which can be exploited by placing a file or a symlink in its place.
Attacker can create his own file to steal the content or can create a symlink to create/modify arbitrary files. On RHEL-7, there is fs.protected_symlinks sysctl provided, which closes this vector. With the setting targ
