Astra Linux – Vulnerability in glibc

NSCD: The NetGroup Cache may terminate the daemon due to a memory allocation failure. The NetGroup Cache Daemon’s NSCD netgroup cache uses xmalloc or xrealloc, and these functions may terminate the process due to a memory allocation failure, resulting in a denial of service for clients. This flaw...

Astra Linux – Vulnerability in wpa

Implementations of EAP-pwd in hostapd before version 2.10, and wpasupplicant before version 2.10, are vulnerable to side-channel attacks due to cache access patterns. NOTE: This issue exists due to an incomplete fix for CVE-2019-9495...

Astra Linux – Vulnerability in Squid

A issue was discovered in Squid 4.9 through 4.17, and also in versions 5.0.6 through 5.6. Due to inconsistent handling of internal URIs, sensitive information about clients using the proxy may be exposed through an HTTPS request to an internal cache manager URL. This issue has been fixed in versi...

Astra Linux – Vulnerability in Squid

A vulnerability was discovered in Squid before versions 4.15 and 5.x before version 5.0.6. Due to incorrect parser validation, this vulnerability allows for a Denial of Service attack against the Cache Manager API. This enables a trusted client to trigger memory leaks, which over time can lead to...
