Debian LTS Advisory DLA-3584-1 [email protected]

Package : netatalk
Version : 3.1.12~ds-3+deb10u4
CVE ID : CVE-2023-42464
Debian Bug : 1052087

Florent Saudel and Arnaud Gatignol discovered a Type Confusion
vulnerability in the Spotlight RPC functions in afpd in Netatalk. When
parsing Spotlight RPC packets, one encoded data structure is a key-value
style dictionary where the keys are character strings, and the values can
be any of the supported types in the underlying protocol. Due to a lack of
type checking in callers of the dalloc_value_for_key() function, which
returns the object associated with a key, a malicious actor may be able to
fully control the value of the pointer and theoretically achieve Remote
Code Execution on the host.

For Debian 10 buster, this problem has been fixed in version
3.1.12~ds-3+deb10u4.

We recommend that you upgrade your netatalk packages.
