Buffer overflow in util.c in libpurple in Pidgin before 2.10.8 allows remote HTTP servers to cause a denial of service (application crash) or possibly have unspecified other impact via an invalid chunk-size field in chunked transfer-coding data.
CVE-2013-6479 1 Pidgin 1 Pidgin 2025-04-11 5.0 MEDIUM N/A
util.c in libpurple in Pidgin before 2.10.8 does not properly allocate memory for HTTP responses that are inconsistent with the Content-Length header, which allows remote HTTP servers to cause a denial of service (application crash) via a crafted response.
CVE-2011-3594 1 Pidgin 2 Libpurple, Pidgin 2025-04-11 4.3 MEDIUM N/A
The g_markup_escape_text function in the SILC protocol plug-in in libpurple 2.10.0 and earlier, as used in Pidgin and possibly other products, allows remote attackers to cause a denial of service (crash) via invalid UTF-8 sequences that trigger use of invalid pointers and an out-of-bounds read, related to interactions with certain versions of glib2.
CVE-2013-6490 1 Pidgin 1 Pidgin 2025-04-11 10.0 HIGH N/A
The SIMPLE protocol functionality in Pidgin before 2.10.8 allows remote attackers to have an unspecified impact via a negative Content-Length header, which triggers a buffer overflow.
