Skype Technologies Skype 1.0.0.100

Integer overflow in Skype client before 1.4.x.84 on Windows, before 1.3.x.17 on Mac OS, before 1.2.x.18 on Linux, and 1.1.x.6 and earlier allows remote attackers to cause a denial of service (crash) via crafted network data with a large Object Counter value, which leads to a resultant heap-based buffer overflow.

Unspecified vulnerability in the skype4com URI handler in Skype before 3.6 GOLD allows remote attackers to execute arbitrary code via "short string values" that result in heap corruption.
