Updated packages in core/updates_testing:ĬVE-2013-4852: putty - SSH handshake heap overflow => Impact on the operation of software that uses PuTTY code (CVE-2013-4852). ThisĪllows remote attackers to cause denial of service, and may have more severe Overflow during the SSH handshake before authentication, caused by improperīounds checking of the length parameter received from the SSH server. Versions of PuTTY - are vulnerable to an integer overflow leading to heap PuTTY versions 0.62 and earlier - as well as all software that integrates these Updated putty packages fix security vulnerability: This vulnerability was discovered and researched by Gergely EberhardtĪnd here I thought PuTTY was just a Windows program. The potential code execution vulnerability has been addressed in WinSCP 5.1.6 Allĭevelopers using PuTTY code are recommended to use revision 9896 or later. This vulnerability has been fixed in the development version of PuTTY. Vulnerability could potentially lead to code execution due to the exception However, in other software that uses PuTTY code, such heap corruptionĬould have more severe effects. The memory corruption, so this bug can only cause a local denial-of-service In the standalone PuTTY client the attacker does not have precise control over The Bignum (in four bytes) into the allocated zero-byte area, also resulting in Would allocate zero bytes in memory via snewn() and attempt to write the size of Similarly, if nbytes was chosen so that w would be -1, the newbn() function Then a large number of bytes wouldīe copied into the data buffer afterwards, resulting in a heap overflow. Newbn() to reserve a very small memory area.

Very small positive number (depending on the value of BIGNUM_INT_BYTES), causing If the value of nbytes was -1 (0xffffffff), the value of w would overflow to a

W = (nbytes + BIGNUM_INT_BYTES - 1) / BIGNUM_INT_BYTES /* bytes->words */ Performed the following arithmetical operation before allocating memory to store Specifically, the bignum_from_bytes() function invoked by getstring() received aĭata buffer along with its length represented by a signed integer (nbytes) and Length without checking that it was not a negative number. The getstring() function in sshrsa.c and sshdss.c read the handshake message all other software that uses vulnerable (revision 9895 or earlier) PuTTY codeĪ malformed size value in the SSH handshake could cause an integer overflow, as Severe impact on the operation of software that uses PuTTY code.
