Sylpheed, Sylpheed-Claws: Buffer overflow in LDIF importer — GLSA 200511-13

Sylpheed and Sylpheed-Claws contain a buffer overflow vulnerability which may lead to the execution of arbitrary code.

Affected packages

mail-client/sylpheed on all architectures
Affected versions < 2.0.4
Unaffected versions >= 2.0.4
mail-client/sylpheed-claws on all architectures
Affected versions < 1.0.5-r1
Unaffected versions >= 1.0.5-r1


Sylpheed is a lightweight email client and newsreader. Sylpheed-Claws is a 'bleeding edge' version of Sylpheed. They both support the import of address books in LDIF (Lightweight Directory Interchange Format).


Colin Leroy reported buffer overflow vulnerabilities in Sylpheed and Sylpheed-Claws. The LDIF importer uses a fixed length buffer to store data of variable length. Two similar problems exist also in the Mutt and Pine addressbook importers of Sylpheed-Claws.


By convincing a user to import a specially-crafted LDIF file into the address book, a remote attacker could cause the program to crash, potentially allowing the execution of arbitrary code with the privileges of the user running the software.


There is no known workaround at this time.


All Sylpheed users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=mail-client/sylpheed-2.0.4"

All Sylpheed-Claws users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=mail-client/sylpheed-claws-1.0.5-r1"
