gssproxy (aka gss-proxy) before 0.8.3 does not unlock cond_mutex before pthread exit in gp_worker_main() in gp_workers.c. NOTE: An upstream comment states "We are already on a shutdown path when running the code in question, so a DoS there doesn't make any sense, and there has been no additional information provided us (as upstream) to indicate why this would be a problem.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - gssproxy (aka gss-proxy) before 0.8.3 does not unlock cond_mutex before pthread exit in gp_worker_main()     in gp_workers.c. NOTE: An upstream comment states We are already on a shutdown path when running the code     in question, so a DoS there doesn't make any sense, and there has been no additional information provided     us (as upstream) to indicate why this would be a problem. (CVE-2020-12658)

Note that Nessus relies on the presence of the package as reported by the vendor.

According to the version of the gssproxy package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - ** DISPUTED ** gssproxy (aka gss-proxy) before 0.8.3     does not unlock cond_mutex before pthread exit in     gp_worker_main() in gp_workers.c. NOTE: An upstream     comment states 'We are already on a shutdown path when     running the code in question, so a DoS there doesn't     make any sense, and there has been no additional     information provided us (as upstream) to indicate why     this would be a problem.'(CVE-2020-12658)

This update for gssproxy fixes the following issues :

  - CVE-2020-12658: Fixed an issue where gssproxy was not     unlocking cond_mutex before pthread exit in     gp_worker_main() (bsc#1180515).

This update was imported from the SUSE:SLE-15-SP1:Update update project.

According to the version of the gssproxy package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  - ** DISPUTED ** gssproxy (aka gss-proxy) before 0.8.3     does not unlock cond_mutex before pthread exit in     gp_worker_main() in gp_workers.c.

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that there was an issue in the gssproxy privilege separation caused by gssproxy not unlocking cond_mutex prior to calling pthread_exit.

For Debian 9 'Stretch', this problem has been fixed in version 0.5.1-2+deb9u1.

We recommend that you upgrade your gssproxy packages.
