Description

The msn_slplink_process_msg function in libpurple/protocols/msn/slplink.c in libpurple, as used in Pidgin (formerly Gaim) before 2.5.9 and Adium 1.3.5 and earlier, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) by sending multiple crafted SLP (aka MSNSLP) messages to trigger an overwrite of an arbitrary memory location. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2009-1376.

Affected products

• Adium: through 1.3.5; 1.2.7, 1.3, 1.3.1, 1.3.2, 1.3.3, 1.3.4
• Pidgin: through 2.5.8; 2.0.0, 2.0.1, 2.0.2, 2.1.0, 2.1.1, 2.2.0 (+15)
