Published: 23 June 2022

Protobuf-c v1.4.0 was discovered to contain an invalid arithmetic shift via the function parse_tag_and_wiretype in protobuf-c/protobuf-c.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via unspecified vectors.

Notes

AuthorNote
mdeslaur
pidgin in precise+ uses embedded libgadu
alexmurray
The various Ubuntu source packages listed against this CVE all contain an embedded copy of protobuf-c but they still needed to be triaged to determine if they actually use their own embedded copy or whether they link against the system libprotobuf-c
mdeslaur
in sudo, only used by sudo_logsrvd, setting priority to low
eslerm
sudo is patched and they sent PR to protobuf-c upstream
