- snapcraft - easily craft snaps
Details
It was discovered that Snapcraft includes the current directory when
configuring LD_LIBRARY_PATH for application commands. If a user were
tricked into installing a malicious snap or downloading a malicious
library, under certain circumstances an attacker could exploit this to
affect strict mode snaps that have access to the library and when
launched from the directory containing the library.
