pgjdbc is an open-source PostgreSQL JDBC Driver. In affected versions, a prepared statement using either PreparedStatement.setTextint, InputStream or PreparedStatemet.setByteaint, InputStream will create a temporary file if the InputStream exceeds 2 kilobytes in size. This temporary file can be...

Astra Linux – Vulnerability in sudo

In Sudo version 1.8.29, the fact that a user has been blocked for example, by using the “!” character in the shadow file instead of a password hash was not taken into consideration. This allows an attacker who has access to a Runas ALL sudoer account to impersonate any blocked user. NOTE: The...

Astra Linux – Vulnerability in Linux 5.10

The nftablesnewset function in net/netfilter/nftablesapi.c in the Linux kernel before version 5.12.13 allows local users to cause a denial of service due to NULL pointer dereferencing and general protection faults, caused by the absence of initialization for nftsetelemexpralloc. A local user can...

Astra Linux – Vulnerability in Sogo
