Title: Tinyproxy Heap Overflow Vulnerability
Severity: HIGH
Description:
Versions 1.3.2 and 1.3.3 of tinyproxy, a small HTTP proxy, exhibit a vulnerability to heap overflow attacks.
A failure to properly validate user-supplied input which arguments a call to sprintf() can allow unexpectedly large amounts of input to a buffer (used to display error messages) to be written past the boundary of the allocated space on the heap.
As a result, it may be possible to execute a denial of service attack, or even to execute arbitrary commands if certain internal memory structures can be successfully overwritten.
Affected Products:
- tinyproxy tinyproxy 1.3.2
- tinyproxy tinyproxy 1.3.3
