string vulnerabilities]
Hello,
Ok, apparently, the primary source of information is the Cert, since :
http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-0254
hrm, I still think the vunerability has nothing to do with
errors_create_window thoo.
Cheers,
endrazine-

>> Synopsis
>> ========
>>
>> xine-ui improperly handles format strings, possibly allowing for the
>> execution of arbitrary code.
>>
>> Background
>> ==========
>>
>> xine-ui is a skin-based user interface for xine. xine is a free
>> multimedia player. It plays CDs, DVDs, and VCDs, and can also decode
>> other common multimedia formats.
>>
>> Affected packages
>> =================
>>
>> -------------------------------------------------------------------
>> Package / Vulnerable / Unaffected
>> -------------------------------------------------------------------
>> 1 xine-ui < 0.99.5_pre20060716 >= 0.99.5_pre20060716
>>
>> Description
>> ===========
>>
>> Due to the improper handling and use of format strings, the
>> errors_create_window() function in errors.c does not safely write data
>> to memory.
>>
>> Impact
>> ======
>>
>> An attacker could entice a user to open a specially crafted media file
>> with xine-ui, and possibly execute arbitrary code.
>>
>> Workaround
>> ==========
>>
>> There is no known workaround at this time.
>>
>> Resolution
>> ==========
>>
>> All xine-ui users should upgrade to the latest version:
>>
>> # emerge --sync
>> # emerge --ask --oneshot --verbose
>> ">=media-video/xine-ui-0.99.5_pre20060716"
>>
