  "details" : [ "url.cpp in libproxy through 0.4.15 is prone to a buffer overflow when PAC is enabled, as demonstrated by a large PAC file that is delivered without a Content-length header.", "A vulnerability was found in libproxy, where a buffer overflow can occur if a server serving a PAC file sends more than 102400 bytes without a Content-Length header, this flaw allows an attacker to trigger an overflow of PAC_HTTP_BLOCK_SIZE (512 bytes), potentially leading to application crashes or unexpected behavior when processing large PAC files." ],
  "statement" : "This vulnerability is rated as moderate because libproxy can overflow its buffer by PAC_HTTP_BLOCK_SIZE (512 bytes) if a server serving a PAC file sends more than 102400 bytes without a Content-Length header, specific conditions related to PAC file handling, and while it could lead to crashes or unexpected behavior, its overall impact is limited.",
