Detail
| Multiple format string vulnerabilities in lib/silcclient/client_entry.c in Secure Internet Live Conferencing (SILC) Toolkit before 1.1.10, and SILC Client before 1.1.8, allow remote attackers to execute arbitrary code via format string specifiers in a nickname field, related to the (1) silc_client_add_client, (2) silc_client_update_client, and (3) silc_client_nickname_format functions. |

| Title: | DSA-1879-1 silc-client/silc-toolkit -- several | ||
| Description: | Several vulnerabilities have been discovered in the software suite for the SILC protocol, a network protocol designed to provide end-to-end security for conferencing services. The Common Vulnerabilities and Exposures project identifies the following problems: An incorrect format string in sscanf used in the ASN1 encoder to scan an OID value could overwrite a neighbouring variable on the stack as the destination data type is smaller than the source type on 64-bit. On 64-bit architectures this could result in unexpected application behaviour or even code execution in some cases. Various format string vulnerabilities when handling parsed SILC messages allow an attacker to execute arbitrary code with the rights of the victim running the SILC client via crafted nick names or channel names containing format strings. An incorrect format string in a sscanf call used in the HTTP server component of silcd could result in overwriting a neighbouring variable on the stack as the destination data type is smaller than the source type on 64-bit. An attacker could exploit this by using crafted Content-Length header values resulting in unexpected application behaviour or even code execution in some cases. Silc-server doesn’t need an update as it uses the shared library provided by silc-toolkit. Silc-client/silc-toolkit in the oldstable distribution is not affected by this problem. For the stable distribution, this problem has been fixed in version 1.1.7-2+lenny1 of silc-toolkit and in version 1.1.4-1+lenny1 of silc-client. For the testing distribution, this problem will be fixed soon. For the unstable distribution, this problem has been fixed in version 1.1.10-1 of silc-toolkit and version 1.1-2 of silc-client. We recommend that you upgrade your silc-toolkit/silc-client packages. | ||
