Description:
Multiple vulnerabilities have been reported in GdkPixBuf, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
1) A variant of a recently disclosed vulnerability in Qt exists within the BMP image processing functionality. This can be exploited to make an affected application enter an infinite loop when a specially crafted BMP image is processed.
2) An input validation error within the "pixbuf_create_from_xpm()" function when decoding XPM images can be exploited to cause an integer overflow when a specially crafted XPM image is processed.
Successful exploitation may in turn result in a heap-based buffer overflow, which potentially allows execution of arbitrary code.
3) A boundary error within the "xpm_extract_color()" function when decoding XPM images can be exploited to cause a stack-based buffer overflow when a specially crafted XPM image is processed.
Successful exploitation may allow execution of arbitrary code.
4) An input validation error within the ICO image decoding functionality can be exploited to cause an integer overflow when a specially crafted ICO image is processed.
Successful exploitation causes an affected application to crash.
Solution:
Secunia is currently not aware of an official updated version, which addresses the vulnerabilities.
However, updates have been issued by various Linux vendors.
